Weighing Cosmological Models with SNe Ia and Gamma Ray Burst Redshift Data
Authors: Gupta Rajendra P.
Published: May 2019

Many models have been proposed to explain the intergalactic redshift using different observational data and different criteria for the goodness-of-fit of a model to the data. The purpose of this paper is to examine several suggested models using the same supernovae Ia data and gamma-ray burst (GRB) data with the same goodness-of-fit criterion and weigh them against the standard Lambda cold dark matter model (ΛCDM). We have used the redshift—distance modulus (z − μ) data for 580 supernovae Ia with 0.015 ≤ z ≤ 1.414 to determine the parameters for each model and then use these model parameter to see how each model fits the sole SNe Ia data at z = 1.914 and the GRB data up to z = 8.1. For the goodness-of-fit criterion, we have used the chi-square probability determined from the weighted least square sum through non-linear regression fit to the data relative to the values predicted by each model. We find that the standard ΛCDM model gives the highest chi-square probability in all cases albeit with a rather small margin over the next best model—the recently introduced nonadiabatic Einstein de Sitter model. We have made (z − μ) projections up to z = 1096 for the best four models. The best two models differ in μ only by 0.328 at z = 1096, a tiny fraction of the measurement errors that are in the high redshift datasets.
A Single-Cycle Adenovirus Type 7 Vaccine for Prevention of Acute Respiratory Disease
Authors: Bullard Brianna L. , Corder Brigette N. , Weaver Eric A.
Published: May 2019

Adenovirus type 7 (Ad7) infection is associated with acute respiratory disease (ARD), especially in military recruits living in close quarters. Recently, several outbreaks of Ad7 infections have occurred in civilian populations, with some cases leading to death. However, the current Ad7 vaccine is licensed for use only in military recruits because it utilizes an orally delivered wild type virus which is shed in the stool for 28 days after immunization. This poses a safety risk due to the possibility of virus spread to vulnerable populations. To address the need for a safer Ad7 vaccine for use in civilian populations, we developed a single-cycle Ad7 virus (scAd7). This scAd7 virus is deleted for the Ad7 fiber protein, so that viruses produced outside of complementing cells lines lack this essential structural protein and have severely reduced infectivity. In vitro studies in noncomplementing A549 cells showed that the scAd7 virus has genomic DNA replication kinetics and Ad7 hexon expression similar to a replication-competent virus; however, virus progeny produced after infection has impaired infectivity. Therefore, this scAd7 virus combines the safety advantages of a replication-defective virus with the increased Ad7 gene expression of a replication-competent virus. Due to these advantages, we believe that scAd7 viruses should be further studied as an alternative, safer Adenovirus 7 vaccine.

Published: May 2019

The cluster concept is well defined in the literature, but its agricultural adaptation has not been detailed. A method is needed, which involves experts into the study, who are able to confirm that the modell is correct and help to define the conceptual gaps. The Delphi technique is suitablefor the task. This is a well-structure, iterative future foresight technique, based on experts opinion about the research topic. The method leads to consensus by all means, but it also can have a negative outcome of the researcher's point of view, that's why we have to formulate scenarios.The aim is not statistically significant result, but to build in new ideas into the modell with brainstorming.
Creating potential agricultural clusters in the Northern Great Plain Region
Authors: Micskei Péter
Published: May 2019

The crisis of the hungarian agricultre is continuous since the ’80s. The compensation is made a dual farm system, which has created barriers to efficient agricultural production. It is confirmed by the economic indexes as well. But the most important natural resources of our country is still the land. Over the past 20 years, the government was not able to work out strategic aims and adequate system for the hungarian agriculture. In the past three decades the clusters has become the most common tool in economic development worldwide. Clusters always base on some local knowledge, and a country can be competitive on the industry in which the resources are concentrated. So the question is, is it possible to „clusterize” theagriculture and through this develop the rural economic.
Circumstances of the establishment of the Eastern Main Channel, water utilisation problems and alternatives
Authors: Nagy Sándor
Published: May 2019

After hundreds of years of drought in the area of Hortobágy and its surroundings brought up the idea of building a channel in Tiszántúl. It started with the idea of an irrigation canal but it ended up in a canal with high importance which can be used in many ways. Because of financial problems the necessary renovations cannot be achieved, and as a side effect the amount of silt in the water started to increase, water exploitation started to decrease, and the construction works started to get spoiled. Guided by the Water Directive the East Main Channel has become one of the most significant surface water base in Hungary. To use its water as drinking water brings up a few questions, like solving the pollution problems which problems have already occured. If we want the East Main Channel to be a solution for a long time, further steps and researches are needed to solve the problem of diverting the huge amount of precipitation of the last few years and miantaining the quality of drinking water.
OPTIMASI NAÏVE BAYES DENGAN PARTICLE SWARM OPTIMIZATION DAN STRATIFIED UNTUK PREDIKSI KREDIT MACET PADA KOPERASI
Authors: Mardiana Tati
Published: May 2019

Dalam bisnis, koperasi memiliki peranan penting dalam meningkatkan perekonomian nasional. Ketidakmampuan anggota untuk membayar angsuran kredit merupakan masalah utama yang terjadi pada koperasi. Akibatnya, terjadi kredit macet. Koperasi dapat menghindari kredit macet dengan membuat prediksi dari anggota koperasi yang berpotensi terlambat membayar kredit. Dalam beberapa penelitian telah menggunakan Naive Bayes untuk masalah klasifikasi karena perhitungan yang efisien, dan  akurasi tinggi. Tetapi Naive Bayes mengasumsikan bahwa semua atribut kelas tidak tergantung pada atribut lainnya. Naive Bayes sesuai untuk masalah klasifikasi dengan atribut besar. Namun, asumsi ini sering tidak dapat dipertahankan dalam masalah klasifikasi nyata. Dalam beberapa dokumen, kinerja Naive Bayes tidak sempurna. Tujuan dari penelitian ini adalah untuk mengoptimalkan metode Naive Bayes menggunakan Particle Swarm Optimization (PSO) dan untuk meningkatkan akurasi dalam memprediksi kredit macet di koperasi. Penelitian ini menggunakan data dari Pusat Data Koperasi (PUSKOPDIT) DKI Jakarta. Data set kredit yang diperoleh sebanyak 565 record dengan 15 prediktor atribut dan 1 atribut kelas. Hasil pengujian dengan confusion matrix dan kurva ROC diperoleh dari nilai akurasi sebesar 86% dan nilai sebesar 0,867 dengan diagnosis klasifikasi baik. Penelitian ini menunjukkan bahwa penggunaan PSO pada NBC untuk memprediksi kredit macet meningkatkan akurasi 21,03% dan AUC sebesar 0,069. Hasil uji T-Test dan Anova menunjukkan bahwa pada dua metode klasifikasi yang diuji memiliki perbedaan yang nyata (signifikan) dalam nilai AUC.
‘Measuring’ Adultery in Article 284 of the Criminal Code
Authors: Desjardins Ajeng Kamaratih
Published: May 2019

After the resolution about the petition of extending the meaning of adultery rampant discussed in the community, Article 284 KUHP is still an interesting article to be reviewed. Diversity in the Indonesian community causes a number of applied regulations must become as fair as possible to be a legal protection for all layers of society, including the regulations ruling the crimes of decency. Different understanding about violating decency in some community groups causes the article in Decency Crime section, especially in adultery case, often marginalizes some groups of community. There are indeed some group that might be potential to be victims of adultery cases if the meaning of adultery ever happens to be broadened. Further in its application, Article 284 KUHP makes the line between morality and crime becomes very thin. This research is done using the approach of feminist legal theory, by reviewing legal text to get an understanding on how sexuality and imagination about the woman victim is projected by law.
Fornication as a criminal conduct in the Criminal Code Draft: Legal Protection versus Criminalization against Women
Authors: Anisah Laili Nur
Published: May 2019

On 14 February 2018 the Draft of the Criminal Code (RKUHP) was adjourned until an undetermined time, several articles deemed to be problematic. One of them is a criminal act of fornication. A new article will convict a denial-men who promises woman he has intercoursed with. Eventhough that article is meant to protect women, on the other hand, it can also be a factor to victimize women as perpetrator. This paper examines the position of women among the articles which will protect women's rights as well as those which criminalize them. This paper is a normative juridical study by using literature review and aims to find the problem and also intend solving it. The result, victimized-women protection Article in RKUHP should carefully be formulated in order not to allow victim women to be criminalized.
Women Facing Legal Cases: Reflection on the Use of Articles 284 and 285 of the Indonesian Criminal Code from the Experiences their Legal Counselor
Authors: Sandiata Bella
Published: May 2019

This paper raises the narrative of experience from legal counselor who once accompanied women victim in cases related to article 284 of the Criminal Code on adultery and article 285 of the Criminal Code on rape. In an interview with the author, four female public lawyers shared their experiences including challenges and obstacles they encountered while advocating cases of adultery and rape. Unacceptable reports, slow-running legal process or even halt in the middle of the process, and facing the attitude of sexism towards victims and public lawyers are some of the obstacles and challenges experienced by the legal counselor of women victims. These public lawyers saw that the criminal law is still not on the side of women and has not provided justice for women. They directly see and experience the difficulty of the legal process running for the article of adultery and rape. Using the feminist legal theory this paper found that law that do not have a gender perspective and siding with women are obstacles to the fulfillment of women victims rights.

This study aims to understand the face of poverty and the use of poverty alleviation funds in regional budgeting. The study was conducted in Makassar City, South Sulawesi by using case study approach. Data collection was done by interview and observation. In-depth interviews were conducted for povertystricken actors and budget managers of poverty funds. This research uses qualitative approach with case study analysis method which according to Creswel can be done through categorization stage, interpretation of pattern formation and naturalistic generaliation. The results show that there are three categories of poor people in the city of Maksassar namely vagrants and beggars, unemployed and poor fishermen. In the potency of policy and government budgeting behavior has been to eradicate the program of alleviation through increasing poverty alleviation budget allocation, but the fulfillment is not necessarily to alleviate poverty in Makassar City. This is because poverty is often used as a tool of exploitation by society and also as a political tool by the government.

Too Good To Be Forgotten
Authors: Op den Kamp Claudy
Published: May 2019

Film archives own, or hold on deposit, many physical works of film, whereas the copyright holder to these might be someone quite different. The colourisation debate of the late 1980s in the US and Als twee druppels water (The Spitting Image, NL 1963, Fons Rademakers), an embargoed film in a public-sector archive, are both examples of this copyright dichotomy between material and intellectual property. The examples expose the archive as a vulnerable place. On the one hand, the archive cannot guarantee a fixed and stable environment for cinematic memories. On the other hand, an inhibited visibility of important works of film that are arguably crucial to an understanding of the history of film is the result if a film archive cannot provide access to its holdings. The examples provide new insights into the wider cultural implications of the intellectual property (IP) system. They demonstrate how IP underpins understandings of public accessibility to (a limited range of) primary source material and their subsequent potential for history making.

Broadcaster’s Dilemma with Archive Asset Management
Authors: Stöger Silvester , Kummer Jean-Christophe
Published: May 2019

With the periodical change of production formats, dissemination platforms and content distribution, broadcasters do face a dilemma, when deciding on an archive format. Very often the actual production format which is supported by current playout systems is found as the answer, and the discussions change every 5 years. As the reality shows that any delivery from the archive is somehow transcoded or rewrapped, a new approach is to rely on one normalised lossless format, which is performant enough to support all business processes around production workflows. Kept in a dedicated Archive Asset management (AAM), legacy essence can be managed inside a central OAIS repository for decades to come. This paper outlines the historical dimension of such a move by listing successful examples from the broadcast industry and archives and giving insights on the ongoing evolution of technology.

Digital conversion of audio, photographic and film collections in sound and audiovisual archives for purposes of preservation and accessibility has been the norm in archival practice since the 1990s. As a result, analog to digital conversion of many music heritage collections, such as the field recordings of Hugh Tracey at the International Library of African Music (ILAM) in South Africa, has been accomplished. With funding secured from the Mellon Foundation, Rand Merchant Bank Expressions Fund, South African National Heritage Council (NAC) and National Research Foundation (NRF), the recordings, films, photos and documents in the Hugh Tracey Collection (hereafter referred to as the Collection) were catalogued and preserved in digital format from 2006-2008. The audio files and 1,000 images in the Collection have been accessible in compressed form via the Internet since late in 2008. Plus, Tracey’s well-known Sound of Africa  and Music of Africa LP series are available as CD compilations and as MP3 files from ILAM and various on-line vendors. Not suprisingly, the many and various opportunities for dissemination digital conversion of field recordings has afforded have brought with them ethical issues for cultural heritage archives which are breifly discussed below.
Compressed Video Quality
Authors: Richardson Iain
Published: May 2019

The concept of video compression goes hand in hand with the switch from analogue to digital video technology that has taken place over the last 25 years. Video delivered to televisions, computers and smartphones typically arrives in a compressed form. The bandwidth and file size savings that compression provides are a significant benefit for consumer and business applications, making it possible to send and receive high-definition video over limited capacity networks. However, for digital archive applications, compression can be problematic, especially when it introduces loss or distortion into a video signal.

 ‘Born digital’ often means ‘born compressed’ and it is increasingly likely that newly-created digital video material will have gone through at least some level of lossy compression. For this reason, it is important to understand the effect of video compression on visual quality. In this paper I will introduce the concept of video compression and its relationship to video image quality. I will consider the factors that influence visual quality, including technical factors such as codecs and coding parameters, as well as the complex and only partly-understood factors that govern our perception of moving images. I will introduce methods of measuring and quantifying video quality and show how it is possible to compare the quality and performance of video processing systems, despite the limitations of quality measurement.
Interactive Visualization to Facilitate Monitoring Longitudinal Survey Data and Paradata

Published: May 2019

Surveys often require monitoring during data collection to ensure progress in meeting goals or to evaluate the interim results of an embedded experiment. Under complex designs, the amount of data available to monitor may be overwhelming and the production of reports and charts can be costly and time consuming. This is especially true in the case of longitudinal surveys, where data may originate from multiple waves. Other such complex scenarios include adaptive and responsive designs, which were developed to act on the results of such monitoring to implement prespecified options or alternatives in protocols. This paper discusses the development of an interactive web-based data visualization tool, the Adaptive Total Design (ATD) Dashboard, which we designed to provide a wide array of survey staff with the information needed to monitor data collection daily. The dashboard was built using the R programming language and Shiny framework and provides users with a wide range of functionality to quickly assess trends. We present the structure of the data used to populate the dashboard, its design, and the process for hosting it on the web. Furthermore, we provide guidance on graphic design, data taxonomy, and software decisions that can help guide others in the process of developing their own data collection monitoring systems. To illustrate the benefits of the dashboard, we present examples from the National Longitudinal Study of Adolescent to Adult Health (Add Health). We also discuss features of the dashboard to be developed for future waves of Add Health.

Authors: Witkowska Dorota , Kompa Krzysztof , Mentel Grzegorz
Published: May 2019

Polish government introduced crucial changes concerning conditions of the pension funds functioning in the years 2011–2014. This article focuses on explaining the impact of these political decisions on efficiency of investment fund market in Poland. Therefore, the article aims (1) to find out if changing in functioning of pension funds also affected the efficiency of mutual funds which provide stable growth investment policy (i.e. similar investment strategy as pension funds) and (2) to check which type of investment funds, pension or mutual, were more efficient in the sense of returns and risks under new regulations. The analysis is provided for selected mutual funds using daily, weekly and monthly returns. The whole period of analysis, years 2009–2015, is divided into six sub-periods according to the three events, that essentially changed the functioning of the pension funds. Statistical tests for in pairs comparisons of returns and risks, and ratios for investment efficiency evaluation were applied. Findings show that pension funds performed better than mutual funds which are managed by the same company. More, the changes of the rules for pension funds’ functioning caused an increase of risk and a decrease of efficiency of the considered investment funds’ portfolios.

We present results of the largest, most comprehensive study ever done of the stellar multiplicity of the most common stars in the Galaxy, the red dwarfs. We have conducted an all-sky volume-limited survey for stellar companions to 1120 M dwarf primaries known to lie within 25 pc of the Sun via trigonometric parallaxes. In addition to a comprehensive literature search, stars were explored in new surveys for companions at separations of 2″–300″. A reconnaissance of wide companions to separations of 300″ was done via blinking archival images. I-band images were used to search our sample for companions at separations of 2″–180″. Various astrometric and photometric methods were used to probe the inner 2″ to reveal close companions. We report the discovery of 20 new companions and identify 56 candidate multiple systems. We find a stellar multiplicity rate of 26.8 ± 1.4% and a stellar companion rate of 32.4 ± 1.4% for M dwarfs. There is a broad peak in the separation distribution of the companions at 4–20 au, with a weak trend of smaller projected linear separations for lower mass primaries. A hint that M-dwarf multiplicity may be a function of tangential velocity is found, with faster moving, presumably older, stars found to be multiple somewhat less often. We calculate that stellar companions make up at least 17% of mass attributed to M dwarfs in the solar neighborhood, with roughly 11% of M-dwarf mass hidden as unresolved companions. Finally, when considering all M-dwarf primaries and companions, we find that the mass distribution for M dwarfs increases to the end of the stellar main sequence.

We report observations of the binary microlensing event OGLE-2018-BLG-0022, provided by the Robotic Observations of Microlensing Events (ROME)/Reactive Event Assessment (REA) Survey, which indicate that the lens is a low-mass binary star consisting of M3 (0.375 ± 0.020 M
⊙) and M7 (0.098 ± 0.005 M
⊙) components. The lens is unusually close, at 0.998 ± 0.047 kpc, compared with the majority of microlensing events, and despite its intrinsically low luminosity, it is likely that adaptive optics observations in the near future will be able to provide an independent confirmation of the lens masses.
Detecting Unresolved Binaries in TESS Data with Speckle Imaging
Authors: Matson Rachel A. , Howell Steve B. , Ciardi David R.
Published: May 2019

The Transiting Exoplanet Survey Satellite (TESS) is conducting a two-year wide-field survey searching for transiting exoplanets around nearby bright stars that will be ideal for follow-up characterization. To facilitate studies of planet compositions and atmospheric properties, accurate and precise planetary radii need to be derived from the transit light curves. Since 40%–50% of exoplanet host stars are in multiple star systems, however, the observed transit depth may be diluted by the flux of a companion star, causing the radius of the planet to be underestimated. High angular resolution imaging can detect companion stars that are not resolved in the TESS Input Catalog, or by seeing-limited photometry, to validate exoplanet candidates and derive accurate planetary radii. We examine the population of stellar companions that will be detectable around TESS planet candidate host stars, and those that will remain undetected, by applying the detection limits of speckle imaging to the simulated host star populations of Sullivan et al. and Barclay et al. By detecting companions with contrasts of Δm ≲ 7–9 and separations of ∼0.″02–1.″2, speckle imaging can detect companion stars as faint as early M stars around A–F stars and stars as faint as mid-M around G–M stars, as well as up to 99% of the expected binary star distribution for systems located within a few hundred parsecs.

We present the first radio/submillimeter detection of monodeuterated methane (CH3D) in Titan’s atmosphere, using archival data from of the Atacama Large Millimeter/submillimeter Array (ALMA). The J

K
 = 21−11 and J

K
 = 20−10 transitions at 465.235 and 465.250 GHz (∼0.644 mm) were measured at significance levels of 4.6σ and 5.7σ, respectively. These two lines were modeled using the Non-linear optimal Estimator for MultivariatE spectral analySIS (NEMESIS) radiative transfer code to determine the disk-averaged CH3D volume mixing ratio = 6.157 × 10−6 in Titan’s stratosphere (at altitudes >130 km). By comparison with the CH4 vertical abundance profile measured by Cassini–Huygens mass spectrometry, the resulting value for D/H in CH4 is (1.033 ± 0.081) × 10−4. This is consistent with previous ground-based and in situ measurements from the Cassini–Huygens mission, though slightly lower than the average of the previous values. Additional CH3D observations at higher spatial resolution will be required to determine a value truly comparable with the Cassini–Huygens CH4 measurements, by measuring CH3D with ALMA close to Titan’s equator. In the post-Cassini era, spatially resolved observations of CH3D with ALMA will enable the latitudinal distribution of methane to be determined, making this an important molecule for further studies.

GRB 160709A is one of the few bright short gamma-ray bursts detected by both the Gamma-ray Burst Monitor and the Large Area Telescope on board the Fermi Gamma-ray Space Telescope. The γ-ray prompt emission of GRB 160709A is adequately fitted by combinations of three distinct components: (i) a nonthermal component described by a power law (PL) with a high-energy exponential cutoff, (ii) a thermal component modeled with a Planck function, and (iii) a second nonthermal component shaped by an additional PL crossing the whole γ-ray spectrum. While the thermal component dominates during ∼0.12 s of the main emission episode of GRB 160709A with an unusually high temperature of ∼340 keV, the nonthermal components dominate in the early and late time. The thermal component is consistent with the photospheric emission resulting in the following parameters: the size of the central engine,

 × 108 cm, the size of the photosphere,

 × 1010 cm, and a bulk Lorentz factor,

, assuming a redshift of 1. The slope of the additional PL spectrum stays unchanged throughout the burst duration; however, its flux decreases continuously as a function of time. A standard external shock model has been tested for the additional PL component using the relation between the temporal and spectral indices (the closure relation). Each set of spectral and temporal indices from two energy bands (200 keV–40 MeV and 100 MeV–10 GeV) satisfies a distinct closure relation. From the closure relation test we derived the index for the electron spectral distribution, p = 2.5 ± 0.1. The interaction of the jet with the interstellar environment is preferred over the interaction with the wind medium.

Changing-look (CL) quasars are a newly discovered class of luminous active galactic nuclei that undergo rapid (≲10 yr) transitions between Type 1 and Type 1.9/2, with an associated change in their continuum emission. We characterize the host galaxies of four faded CL quasars using broadband optical imaging. We use gri images obtained with the Gemini Multi-Object Spectrograph on Gemini North to characterize the surface brightness profiles of the quasar hosts and search for [O iii] λ4959, λ5007 emission from spatially extended regions, or voorwerpjes, with the goal of using them to examine past luminosity history. Although we do not detect, voorwerpjes surrounding the four quasar host galaxies, we take advantage of the dim nuclear emission to characterize the colors and morphologies of the host galaxies. Three of the four galaxies show morphological evidence of merger activity or tidal features in their residuals. The three galaxies that are not highly distorted are fit with a single Sérsic profile to characterize their overall surface brightness profiles. The single-Sérsic fits give intermediate Sérsic indices between the n = 1 of disk galaxies and the n = 4 of ellipticals. On a color–magnitude diagram, our CL quasar host galaxies reside in the blue cloud, with other active galactic nucleus (AGN) host galaxies and star-forming galaxies. On a color-Sérsic index diagram the CL quasar hosts reside with other AGN hosts in the “green valley.” Our analysis suggests that the hosts of CL quasars are predominantly disrupted or merging galaxies that resemble AGN hosts, rather than inactive galaxies.
Normal Modes of Transverse Coronal Loop Oscillations from Numerical Simulations. I. Method and Test Case
Authors: Rial S. , Arregui I. , Oliver R. , Terradas J.
Published: May 2019

The purpose of this work is to develop a procedure to obtain the normal modes of a coronal loop from time-dependent numerical simulations with the aim of better understanding observed transverse loop oscillations. To achieve this goal, in this paper we present a new method and test its performance with a problem for which the normal modes can be computed analytically. In a follow-up paper, the application to the simulations of Rial et al. is tackled. The method proceeds iteratively and at each step consists of (i) a time-dependent numerical simulation followed by (ii) the Complex Empirical Orthogonal Function (CEOF) analysis of the simulation results. The CEOF analysis provides an approximation to the normal mode eigenfunctions that can be used to set up the initial conditions for the numerical simulation of the following iteration, in which an improved normal mode approximation is obtained. The iterative process is stopped once the global difference between successive approximate eigenfunctions is below a prescribed threshold. The equilibrium used in this paper contains material discontinuities that result in one eigenfunction with a jump across these discontinuities and two eigenfunctions whose normal derivatives are discontinuous there. After six iterations, the approximations to the frequency and eigenfunctions are accurate to ≲0.7% except for the eigenfunction with discontinuities, which displays a much larger error at these positions.
Massive Young Stellar Objects and Outflow in the Infrared Dark Cloud G79.3+0.3

Published: May 2019

G79.3+0.3 is an infrared dark cloud in the Cygnus-X complex that is home to massive deeply embedded young stellar objects (YSOs). We have produced a Submillimeter Array (SMA) 1.3 mm continuum image and 12CO line maps of the eastern section of G79.3+0.3 in which we detect five separate YSOs. We have estimated physical parameters for these five YSOs and others in the vicinity of G79.3+0.3 by fitting existing photometry from Spitzer, Herschel, and ground-based telescopes to spectral energy distribution models. Through these model fits we find that the most massive YSOs seen in the SMA 1.3 mm continuum emission have masses in the 5–6 M
☉ range. One of the SMA sources was observed to power a massive collimated 12CO outflow extending at least 0.94 pc in both directions from the protostar, with a total mass of 0.83 M
☉ and a dynamical timescale of 23 kyr.
Data-driven Spectroscopy of Cool Stars at High Spectral Resolution
Authors: Behmard Aida , Petigura Erik A. , Howard Andrew W.
Published: May 2019

The advent of large-scale spectroscopic surveys underscores the need to develop robust techniques for determining stellar properties (“labels,” i.e., physical parameters and elemental abundances). However, traditional spectroscopic methods that utilize stellar models struggle to reproduce cool (<4700 K) stellar atmospheres due to an abundance of unconstrained molecular transitions, making modeling via synthetic spectral libraries difficult. Because small, cool stars such as K and M dwarfs are both common and good targets for finding small, cool planets, establishing precise spectral modeling techniques for these stars is of high priority. To address this, we apply The Cannon, a data-driven method of determining stellar labels, to Keck High Resolution Echelle Spectrometer spectra of 141 cool (<5200 K) stars from the California Planet Search. Our implementation is capable of predicting labels for small (<1 R
⊙) stars of spectral types K and later with accuracies of 68 K in effective temperature (T
eff), 5% in stellar radius (R
*), and 0.08 dex in bulk metallicity ([Fe/H]), and maintains this performance at low spectral resolutions (R < 5000). As M dwarfs are the focus of many future planet-detection surveys, this work can aid efforts to better characterize the cool star population and uncover correlations between cool star abundances and planet occurrence for constraining planet formation theories.

We present a critical review of the determination of fundamental parameters of white dwarfs discovered by the Gaia mission. We first reinterpret color–magnitude and color–color diagrams using photometric and spectroscopic information contained in the Montreal White Dwarf Database (MWDD), combined with synthetic magnitudes calculated from a self-consistent set of model atmospheres with various atmospheric compositions. The same models are then applied to measure the fundamental parameters of white dwarfs using the so-called photometric technique, which relies on the exquisite Gaia trigonometric parallax measurements, and photometric data from Panoramic Survey Telescope And Rapid Response System, Sloan Digital Sky Survey, and Gaia. In particular, we discuss at length the systematic effects induced by these various photometric systems. We then study in great detail the mass distribution as a function of effective temperature for the white dwarfs spectroscopically identified in the MWDD, as well as for the white dwarf candidates discovered by Gaia. We pay particular attention to the assumed atmospheric chemical composition of cool, non-DA stars. We also briefly revisit the validity of the mass–radius relation for white dwarfs and the recent discovery of the signature of crystallization in the Gaia color–magnitude diagram for DA white dwarfs. We finally present evidence that the core composition of most of these white dwarfs is, in bulk, a mixture of carbon and oxygen, an expected result from stellar evolution theory, but never empirically well established before.
Unbiased Cosmic Opacity Constraints from Standard Sirens and Candles
Authors: Wei Jun-Jie
Published: May 2019

The observation of Type Ia supernovae (SNe Ia) plays an essential role in probing the expansion history of the universe. But the possible presence of cosmic opacity can degrade the quality of SNe Ia. The gravitational-wave (GW) standard sirens, produced by the coalescence of double neutron stars and black hole–neutron star binaries, provide an independent way to measure the distances of GW sources, which are not affected by cosmic opacity. In this paper, we first propose that combining the GW observations of third-generation GW detectors with SN Ia data in similar redshift ranges offers a novel and model-independent method to constrain cosmic opacity. Through Monte Carlo simulations, we find that one can constrain the cosmic opacity parameter κ with an accuracy of σ

κ
 ∼ 0.046 by comparing the distances from 100 simulated GW events and 1048 current Pantheon SNe Ia. The uncertainty of κ can be further reduced to ∼0.026 if 800 GW events are considered. We also demonstrate that combining 2000 simulated SNe Ia and 1000 simulated GW events could result in much severer constraints on the transparent universe, for which κ = 0.0000 ± 0.0044. Compared to previous opacity constraints involving distances from other cosmic probes, our method using GW standard sirens and SN Ia standard candles at least achieves competitive results.
First Abundance Measurement of Organic Molecules in the Atmosphere of HH 212 Protostellar Disk

Published: May 2019

HH 212 is one of the well-studied protostellar systems, showing the first vertically resolved disk with a warm atmosphere around the central protostar. Here we report a detection of nine organic molecules (including newly detected ketene, formic acid, deuterated acetonitrile, methyl formate, and ethanol) in the disk atmosphere, confirming that the disk atmosphere is, for HH 212, the chemically rich component, identified before at a lower resolution as a “hot corino.” More importantly, we report the first systematic survey and abundance measurement of organic molecules in the disk atmosphere within ∼40 au of the central protostar. The relative abundances of these molecules are similar to those in the hot corinos around other protostars and in Comet Lovejoy. These molecules can be either (i) originally formed on icy grains and then desorbed into gas phase or (ii) quickly formed in the gas phase using simpler species ejected from the dust mantles. The abundances and spatial distributions of the molecules provide strong constraints on models of their formation and transport in star formation. These molecules are expected to form even more complex organic molecules needed for life and deeper observations are needed to find them.
