Authors: Corrêa Mariane Mendes Luiz , Freitas Tatiane Cristina Rodrigues , Silva Siomara Aparecida da
Published: July 2020

Introdução: A educação física escolar possui um vasto conteúdo formado pelas manifestações corporais. Os mais comuns - geralmente escolhidos pelos professores, são os esportes coletivos - futebol/futsal, basquetebol, voleibol e handebol, que formam uma monocultura de cinco modalidades. As atividades propostas nas aulas necessitam incluir novas experiências esportivas, maximizando os alcances dos conteúdos da cultura corporal através dos esportes. Objetivo: Verificar as possibilidades da inserção dos esportes de raquete nas aulas de Educação Física Escolar dos anos finais do ensino fundamental, 7º e 8º anos. Métodos: Através de observações da aplicação de atividades em vinte aulas, foi realizada a análise de conteúdo. Resultados: Ao considerar as anotações do diário de campo percebeu-se que inserir novos conteúdos nas aulas é uma barreira a ser ultrapassada. Quebrar o paradigma da monocultura não é uma tarefa fácil, principalmente por existir a dificuldade de aquisição dos materiais direcionados à execução das habilidades de rebatida, que não são comuns no almoxarifado da escola. Mas, como forma de minimizar tais dificuldades, esses materiais podem ser confeccionados pelos próprios alunos, despertando neles a curiosidade e o entusiasmo pela prática de atividades pouco desenvolvidas. Este aspecto facilitador, somado ao fato de que as atividades não são totalmente coletivas, provocou maior aceitação e participação nas aulas. Conclusão: Portanto, a inserção de novos conteúdos nas aulas de educação física é uma tarefa árdua, mas se aplicada com uma metodologia adequada, materiais atraentes e atividades criativas, se torna uma tarefa interessante e incentivadora, proporcionando a adesão dos alunos às aulas.

Objetivo: identificar o imaginário social transmitido pela mídia sobre atletas consideradas heroínas esportivas e identificar os discursos sobre as diferenças de gênero transmitidas pela mídia nos Jogos Olímpicos Rio 2016. Métodos: trata-se de uma pesquisa descritiva de análise documental, cuja estratégia metodológica consistiu na busca de matérias sobre heroínas Rio 2016 no site Google. As reportagens foram analisadas utilizando-se a Análise da Ordem do Discurso, de Michel Foucault. Resultados: os princípios da inversão, descontinuidade, especificidade e exterioridade, estabelecidos por Foucault, estavam presentes nos discursos analisados. Nas reportagens, as mulheres consideradas heroínas esportivas tiveram destaque quando conquistaram a primeira medalha olímpica do país de origem, quando realizaram grandes atuações em partidas decisivas e quando superaram abuso sexual. Conclusão: mesmo sendo consideradas heroínas esportivas, a imagem dessas mulheres foi associada à figura masculina. Isso evidencia a necessidade de avanços no quesito igualdades de direito entre homens e mulheres na sociedade.ABSTRACT. The contemporary myth of sports heroin: from war to podium. Objective: to identify the social imaginary transmitted by the media about women athletes considered athletic heroines and to identify the discourses on the gender differences transmitted by the media in the Rio 2016 Olympic Games. Methods: this is a descriptive research of documentary analysis, whose methodological strategy consisted in the search of stories about Rio 2016 heroines in the Google site. The reports were analyzed using the Discourse Order Analysis of Michel Foucault. Results: the principles of inversion, discontinuity, specificity and exteriority, as established by Foucault, were present in the discourses analyzed. In the reports, women considered to be sport heroines were highlighted when they won the first Olympic medal in the country of origin, when they performed great plays in decisive games and when they overcame sexual abuse. Conclusion: however, even though they were considered sport heroines, the image of these women was associated with the male figure. This highlights the need for advances in the area of equal rights between men and women in society.

Authors: Fitio Volodymyr , Yaremchuk Iryna , Vernyhor Oleksandr , Bobitski Yaroslav
Published: July 2020

In this work, the analytical expressions describing experimental data of silver, gold, copper and aluminum dielectric permittivity in a wide spectral range are presented. A comparison of samples production techniques, the measurement methods and the experimental data of different authors led to the conclusion that the most valid data are given by McPeak et al. (ACS Photonics 2(3), 2015, pp. 326–333) and Babar et al.(Appl. Opt. 54(3), 2015, pp. 477–481), which are close to each other. Thus, the analytical expressions for silver, gold, copper and aluminum dielectric permittivity spectral dependences are based on it. The spectral range in which the dielectric permittivity is represented by the corresponding analytical expression is divided into several intervals. There is a specific function for each wavelength range.

Published: July 2020

In the presented work, the influence of the quantum well and barrier thicknesses on optical characteristics of InGaAs/AlInAs superlattices was reported. Six different structures of In0.53Ga0.47As/Al0.48In0.52As superlattices lattice-matched to InP were grown by low pressure metal organic vapour phase epitaxy (LP-MOVPE). Optical properties of the obtained structures were examined by means of photoluminescence spectroscopy. This technique allows quick, simple and non-destructive measurements of radiative optical transitions in different semiconductor heterostructures. The analysis of recorded photoluminescence spectra revealed the influence of the quantum well and barrier thicknesses on the emission line energy.

Authors: Pruszyńska-Karbownik Emilia , Gębski Marcin , Marciniak Magdalena , Lott James A. , Czyszanowski Tomasz
Published: July 2020

In this paper, we present experimental results of spontaneous emission clamping in the threshold for vertical-cavity surface-emitting lasers (VCSELs) with oxide current confinement. We show that the spontaneous emission not wholly clamps in the threshold. We propose a new method for determining the threshold current value using the study of the clamping phenomena. This method has an advantage over the commonly used methods in the accuracy because the current of the spontaneous emission clamping is betted defined than the current of the slope change of the stimulated emission light-current curve. The estimated uncertainty of the method is no more than 20 µA.
Photoluminescence and Raman spectroscopies as an optical approach of stress determining in MOVPE grown quantum cascade laser structures
Authors: Łozińska Adriana , Badura Mikołaj , Jadczak Joanna , Bielak Katarzyna , Ściana Beata
Published: July 2020

In the presented work, an optical approach of stress determining in metalorganic vapor phase epitaxy (MOVPE) grown quantum cascade laser (QCL) structures was reported. In the case of such sophisticated structures containing hundreds of thin layers, it is important to minimize the stress generated in the QCL core. Techniques enabling determination of stress in such thin layers as those described in the article are photoluminescence and Raman spectroscopies. Based on Raman shift or changes in photoluminescence signal, it is possible to analyze stress occurring in the structure.

Published: July 2020

The influence of using InGaN waveguides on blue laser diodes was theoretically studied using 1D drift diffusion model and 2D optical mode calculation. Despite of the known effect of increased confinement of an optical mode, especially for long wavelengths, an unexpected influence on the efficiency of carrier injection into the active region is discussed. It is found that InGaN-AlGaN interface is crucial to achieving high injection efficiency. A numerical model is created, which describes the influence of InGaN waveguide and Mg doping of electron blocking layer on basic properties of laser diodes. It is found that an increase of injection efficiency allows to reduce the doping level in an electron blocking layer and take advantage of decreased optical losses.

Background. There are few descriptions of the clinical presentation and evolution of consecutive SARS-CoV-2 infections with a long-enough follow up.
Methods. Description of the first consecutive 100 patients with microbiologically-proven COVID-19 in a large hospital in Madrid, Spain including a minimum of two-month follow up.
Results. The median age of the patients (52% males) was 61.5 years (IQR=39.5-82.0) and the median BMI was 28.8 kg/m2 (IQR=24.7-33.7). Overall 72% of the patients had one or more co-morbid conditions with a median age-adjusted Charlson index of 2 (IQR=0-5.7). Five patients (5%) were immunosuppressed. The most common symptoms at the time of diagnosis were fever (80.0%), cough (53.0%) and dyspnea (23.0%). The median O2 saturation at the time of first examination was 94% (IQR=90-97). Chest X-ray on admission was compatible with pneumonia in 63% of the cases (bilateral in 42% and unilateral in 21%). Overall, 30% were managed at home and 70% were admitted to the hospital. Thirteen patients were admitted to the ICU with a median of 11 days of stay in the Unit (IQR=6.0-28.0). CALL score of our population ranged from 4 to 13. Overall, 60.0% of patients received antibiotic treatment and 66.0%, empirical antiviral treatment, mainly with lopinavir/ritonavir (65%) or hydroxychloroquine (42%). Mortality, with a minimum of 60 days of follow up, was 23%. The median age of the deceased patients was 85 years (IQR=79-93).
Conclusions. We found a high mortality in the first 100 patients diagnosed with COVID-19 at our institution, associated with advanced age and the presence of serious underlying diseases.
The Dynamic Interplay Between Mast Cells, Aging/Cellular Senescence, and Liver Disease
Authors: Kundu Debjyoti , Kennedy Lindsey , Meadows Vik , Baiocchi Leonardo , Alpini Gianfranco , Francis Heather
Published: July 2020

Mast cells are key players in acute immune responses that are evidenced by degranulation leading to a heightened allergic response. Activation of mast cells can trigger a number of different pathways contributing to metabolic conditions and disease progression. Aging results in irreversible physiological changes affecting all organs, including the liver. The liver undergoes senescence, changes in protein expression, and cell signaling phenotypes during aging, which regulate disease progression. Cellular senescence contributes to the age-related changes. Unsurprisingly, mast cells also undergo age-related changes in number, localization, and activation throughout their lifetime, which adversely affects the etiology and progression of many physiological conditions including liver diseases. In this review, we discuss the role of mast cells during aging, including features of aging (e.g., senescence) in the context of biliary diseases such as primary biliary cholangitis and primary sclerosing cholangitis and nonalcoholic fatty liver disease.
Antecedents and Consequences of Souvenir Authenticity
Authors: Li Xiangping , Yang Fiona X. , Lau Virginia Meng-Chan
Published: July 2020

This study aims to examine the relationships between souvenir authenticity and its antecedents, as well as its consequences, using a consumer-based model of authenticity. A quantitative survey was conducted with tourists visiting Macao, and a valid sample of 275 tourists was used for
data analysis. Empirical results indicate that there is a positive relationship between souvenir authenticity and its antecedents, namely souvenir-purchasing motivations. In addition, souvenir authenticity is positively related to its consequences, including existential authenticity, cultural
destination image, and destination loyalty. While the results lend support to the consumer-based model of authenticity in the context of souvenirs, the findings also offer some practical implications for souvenir retailers as well as destination marketers.
Consumer Motivation to Choose Airbnb Plus Homes
Authors: Jiang Yangyang , Lyu Cenhua
Published: July 2020

Airbnb Plus is an upscale lodging service offered by the Airbnb platform. The Airbnb Plus business has become a noteworthy marketing phenomenon and the customer behavior of Airbnb Plus necessitates academic attention. Drawing on the theory of planned behavior, a conceptual model is
established and tested to provide insights into the consumer's motivation and intention to adopt an upscale marketing offering of the accommodation sharing economy system. A total of 342 valid responses were collected through an online survey. The results show that economic benefits, home
benefits, authenticity, hedonism, and quality each positively influence the consumer's intention to adopt Airbnb Plus. In addition, hedonism emerges as the strongest predictor of the intention to choose Airbnb Plus homes. Neither social interaction nor social status has a significant effect
on the intention to use Airbnb Plus. Theoretical contributions and practical implications of this study are discussed.

Published: July 2020

The effect of nature-based tourism on wildlife has been the focus of much attention. Studies have demonstrated how boat-based cetacean-watching tourism can cause both short-term and long-term effects on targeted populations. However, limited attention has been given to the effect of swim-with activities on humpback whales (Megaptera novaeangliae). This study qualified whale responses to swim-with activities off Reunion Island during the 2018 humpback whales breeding season. We used both under- and above-water videos collected from social media outlets, commercial whale-watching operators, and audiovisual professionals. We documented a high rate of agonistic whale behaviors (during 42.1% of all observations;n= 164) towards swimmers within videos containing swim-with events. We documented seven agonistic behaviors including threat, attack, or defense behaviors that were predominantly exhibited by mother/calf groups (73.8%;n= 121) and by singletons (16.5%;n= 27). Pectoral shears (27.4%) and fluke thrashes (23.2%) were the most exhibited agonistic whale behaviors aimed towards swimmers, both of which pose a danger and serious injury to swimmers. During swim-with attempts whales changed their behavioral state (82.3%,n= 159) and used avoidance tactics to avoid swimmers (56.1%,n= 92). Whales exhibited a higher rate of agonistic behaviors when swim groups were active and dispersed, in contrast to when they were quiet and compact. To mitigate whale disturbance and improve swimmer safety, we recommend avoiding swimming with whale groups containing calfs. Our findings support the implementation of strong regulations and educational tools to ensure a sustainable practice of whale watching off the Reunion Island.

The role of gold atom concentration in the processes of formation of Cu-Au nanoparticles from the gas phase
Authors: Gafner Yuri Ya , Gafner Svetlana L , Ryzkova Darya A , Nomoev Andrey V
Published: July 2020

Currently, bimetallic nanoparticles have been widely used in various fields of nanotechnology, but the main area of their application continues to be the catalysis of chemical reactions. However, it soon became clear that the catalytic activity of nanoalloys very much depends on their size, chemical composition, and shape. Therefore, the question of controlling the synthesis of bimetallic nanoparticles to obtain particles of the desired size, spatial structure, and chemical composition is very acute. In the synthesis of the Cu-Au studied by us, nanoparticles can occur either through chemical or physical methods, each of which has its own drawbacks. Though it is very difficult to achieve the required target chemical composition of nanoparticles during chemical synthesis, their size can be stabilized quite well. In turn, physical synthesis methods mainly allow you to withstand the required chemical composition, but the size of the resulting particles varies significantly. To solve this contradiction, we studied the formation of Cu-Au nanoparticles of different chemical compositions from a gaseous medium using computer Molecular Dynamics simulation to determine the effect of the concentration of gold atoms on the size and actual chemical composition of the formed bimetallic nanoparticles.

SYNERGETIC APPROACH TO THE STUDY OF CONTROL SYSTEMS
Authors: Kravchenko Y. , Leshchenko O. , Trush A. , Dukhnovska K. , Kovtun O.
Published: July 2020

The paper considers a new direction of scientific research - "synergetics". The key provisions and its development as a science are considered. The focus is on open feedback systems as objects of research. The properties of these systems - openness, nonlinearity, dissipation and multidimensionality, allow the use of a synergistic approach in the study. Due to new trends in information technology in recent years, interest in the new architecture of Software Defined Networks has grown. A programmable controller is used as a control mechanism for SDN networks. The connection between the logical controller and the physical network is made using the OpenFlow protocol.
The graph of the network topology is presented as a set of key parameters that come to the controller. From the set of parameters, the key ones used in the study are selected. The dynamics of the ratio of key parameters under the condition of optimizing the network infrastructure is studied. The dynamics of the network corresponding to the stability condition is investigated by the methods of synergetic control theory. SDN network control is formed by methods based on the principle of self-organization of nonlinear systems. As a result, synergetic control is synthesized to increase the resistance of the control system to destructive influences. Based on the selected dynamic invariant, the possibility of providing the selection of the parameter of the SDN network management system for the transition to a controlled state is shown.

Authors: Kolesnikov O , Biloshchytskyi A. , Gogunskii A. , Khomiak A.
Published: July 2020

The paper presents the theoretical foundations of creating the educational environment of an educational institution using the project approach at the stage of building models and displaying communications in the information environment in accordance with
GOST R 54869 - 2011. The article considers the Markov process with discrete states, discrete-time, and homogeneous characteristics of transition probabilities. The latter means that the transition probabilities for the series do not change over time. The set of specific values of transition probabilities characterizes the level of organizational maturity of the project. A unified method of transformation of iconographic models of states of complex systems in the Markov chain is developed. The method has sufficient simplicity of the mathematical apparatus and high reliability of the mapping of the phenomenological properties of stochastic systems. The developed model allows us to study the features of communication processes in competently oriented information training systems in the educational environment of educational institutions and to obtain a quantitative assessment of the effectiveness of such systems. The management of educational activities of an educational institution should be considered as a continuous process of improving its activities in the conditions of modern competition in the market of educational services. The proposed model, based on the project approach, will allow the efficient use of material resources, as well as flexibly respond to any changes both within the educational institution and in the external environment.

Background: Hot water epilepsy is a type of reflex epilepsy which generally occurs with
pouring water on the body during bath.
Objective: The aim of this study is to evaluate the clinical and electrophysiological features,
treatment, and outcome of the pediatric patients with diagnosis of hot water epilepsy.
Methods: Patients were followed and treated at Erciyes University, between January 2010
and January 2016.
Results: There were 15 patients total, included 9 (60%) boys and 6 (40%) girls. The average
age at diagnosis was 30 months (range: 13-60 months). The follow-up period was 16 months
(range: 12-48 months). Seven patients (46.6%) had focal seizures with impaired consciousness,
four (26.7%) had focal seizure and four (26.7%) had focal starting and generalized tonic-clonic
continuing seizures. Seven patients (46.6%) had abnormal interictal EEG findings, ranged
from unilateral slowing of the background activity to bilateral sharp wave. Intermittent clobazam
treatment (0.8-1.2 mg/kg) was given to 13 patients (86.7%). Other epileptic treatments were
used in 5 (33.3%) patients. Three patients (20.0%) developed nonreflex seizures during followup period.
Conclusions: Intermittent clobazam prophylaxis prior to hot water bath, as well as changing
bathing habits can be effective in pediatric patients with hot water epilepsy.

Background: In addition to body mass index (BMI), fat mass (FM), fat-free mass (FFM), and
their index may be used to predict metabolic health risks. The aim of this study is to define ageand gender-specific FM, fat mass index (FMI), FFM and fat-free mass index (FFMI) percentiles
for heatly Turkish children and adolescents.
Methods: A total of 4028 (2252 girls, 1776 boys) participant aged 6–17 years were recruited.
The body composition was evaluated by bioelectrical impedans. FM, FMI, FFM and FFMI
percentiles were produced.
Results: FM, FFM, FMI and FFMI percentiles were calculated. FMI and FM were female
predominance through 6 to 17 years. The differences in 3rd-97th percentiles of FFMI were 4.06–7.20 kg/m2
respectively for males, where this difference was 4.06-6.95 kg/m2
for females.
We checked the age-specific contribution of FMI, FFMI to BMI and fat% with Hattori chart and
found that children with similar BMI may lie in different fat%.
Conclusions: Since FM and FFM are important for the evaluation of body composition, in
addition to BMI and body fat%, FM and FFM percentiles are required as local reference.
Therefore, this study provides normative data for body FM, FMI, FFM and FFI percentiles.
opción por los pobres: algunas implicaciones para la pedagogía cristiana
Authors: Jiménez Rodríguez Manuel José
Published: July 2020

Los obispos latinoamericanos reunidos en Puebla (México, 1979), en el marco de la opción preferencial por los pobres que toman en continuidad con Medellín (Colombia, 1968), afirman que dicha opción ha ayudado a la Iglesia a descubrir el potencial evangelizador de los pobres. Hace pocos años el papa Francisco en la encíclica La alegría del Evangelio (2013), retoma la idea del potencial evangelizador de los pobres.

El presente texto quiere aportar una breve reflexión al modo como la opción por los pobres impacta de modo radical la pedagogía cristiana, aquella en donde se forma el discípulo, pero también aquella en la que la Iglesia entra en diálogo con el mundo, de modo especial el ámbito escolar formal. No ofrece indicaciones prácticas sobre cómo la opción por los pobres se hace presente en los planes de formación, en los proyectos pedagógicos o en el currículo del área. Pero sí se espera que, a partir de ellas, sean los agentes educativos implicados en estas áreas quienes tomen decisiones prácticas y de terreno al respecto.

Based on number, probably Dhaka Medical College Hospital is one of the top institute in the world, where highest number of tracheostomy is being operated (3-10 per day). So, our purpose of this study is to describe our own experiences, regarding indication, complication , decanulation, morbidity and mortality following tracheostomy and to compare the results with the institutes of other countries of the world. Methods It is a prospective observational study, conducted at Dhaka Medical College Hospital from July 2014 to June 2019. Data were collected from the Registers of emergency and elective operation theatre, indoor, intensive care unit (ICU) and medical record room (where file of all patients are being kept for long time). SPSS software was used for data processing and analysis. Prior to the study ethical approval was obtained from Ethical review committee. Results Total 257 patients were selected for the study. Among them 210 (81.71%) were male and 47 (18.29%) were female. Most of the patients were elderly, above sixty years. Commonest indication for tracheostomy were upper airway obstruction due to laryngeal or other head neck cancer in 70.04% of patients. Next important indication was upper airway obstruction due to trauma in 24.9% cases. Most of the time (82.88%) we had to perform Emergency tracheostomy. Longitudinal or
Two Views of the Radius Gap and the Role of Light Curve Fitting
Authors: Petigura Erik A.

Recently, several groups have resolved a gap that bifurcates planets between the size of Earth and Neptune into two populations. The location and depth of this feature is an important signature of the physical processes that form and sculpt planets. In particular, planets residing in the radius gap are valuable probes of these processes as they may be undergoing the final stages of envelope loss. Here, we discuss two views of the radius gap by Fulton & Petigura (F18) and Van Eylen et al. (V18). In V18, the gap is wider and more devoid of planets. This is due, in part, to V18's more precise measurements of planet radius

are largest at high impact parameter (

) and often exceed 10%. This motivates excluding high-b planets from demographic studies, but identifying such planets from long-cadence photometry alone is challenging. We show that transit duration can serve as an effective proxy, and we leverage this information to enhance the contrast between the super-Earth and sub-Neptune populations.

The possible detection of a compact object in the remnant of SN 1987A presents an unprecedented opportunity to follow its early evolution. The suspected detection stems from an excess of infrared emission from a dust blob near the compact object’s predicted position. The infrared excess could be due to the decay of isotopes like 44Ti, accretion luminosity from a neutron star or black hole, magnetospheric emission or a wind originating from the spin down of a pulsar, or to thermal emission from an embedded, cooling neutron star (NS 1987A). It is shown that the last possibility is the most plausible as the other explanations are disfavored by other observations and/or require fine-tuning of parameters. Not only are there indications that the dust blob overlaps the predicted location of a kicked compact remnant, but its excess luminosity also matches the expected thermal power of a 30 yr old neutron star. Furthermore, models of cooling neutron stars within the minimal cooling paradigm readily fit both NS 1987A and Cas A, the next-youngest known neutron star. If correct, a long heat transport timescale in the crust and a large effective stellar temperature are favored, implying relatively limited crustal n-1S0 superfluidity and an envelope with a thick layer of light elements, respectively. If the locations do not overlap, then pulsar spin down or accretion might be more likely, but the pulsar’s period and magnetic field or the accretion rate must be rather finely tuned. In this case, NS 1987A may have enhanced cooling and/or a heavy-element envelope.
Stellar Characterization of Keck HIRES Spectra with The Cannon

Published: July 2020

To accurately interpret the observed properties of exoplanets, it is necessary to first obtain a detailed understanding of host star properties. However, physical models that analyze stellar properties on a per-star basis can become computationally intractable for sufficiently large samples. Furthermore, these models are limited by the wavelength coverage of available spectra. We combine previously derived spectral properties from the Spectroscopic Properties of Cool Stars (SPOCS) catalog with generative modeling using The Cannon to produce a model capable of deriving stellar parameters (

, T
eff, and

) and 15 elemental abundances (C, N, O, Na, Mg, Al, Si, Ca, Ti, V, Cr, Mn, Fe, Ni, and Y) for stellar spectra observed with Keck Observatory’s High Resolution Echelle Spectrometer (HIRES). We demonstrate the high accuracy and precision of our model, which takes just ∼3 s to classify each star, through cross-validation with pre-labeled spectra from the SPOCS sample. Our trained model, which takes continuum-normalized template spectra as its inputs, is publicly available at https://github.com/malenarice/keckspec. Finally, we interpolate our spectra and employ the same modeling scheme to recover labels for 477 stars using archival stellar spectra obtained prior to Keck’s 2004 detector upgrade, demonstrating that our interpolated model can successfully predict stellar labels for different spectrographs that have (1) sufficiently similar systematics and (2) a wavelength range that substantially overlaps with that of the post-2004 HIRES spectra.
Hurricane Genesis is Favorable on Terrestrial Exoplanets Orbiting Late-type M Dwarf Stars

Published: July 2020

Hurricanes are one of the most extreme storm systems that occur on Earth, characterized by strong rainfall and fast winds. The terrestrial exoplanets that will be characterized with future infrared space telescopes orbit M dwarf stars. As a result, the best observable terrestrial exoplanets have vastly different climates from Earth, with a large dayside-to-nightside irradiation contrast and relatively slow rotation. Hurricanes may affect future observations of terrestrial exoplanets because they enhance the vertical transport of water vapor and could influence ocean heat transport. In this work, we explore how the environment of terrestrial exoplanets orbiting M dwarf stars affects the favorability of hurricane genesis (formation). To do so, we apply metrics developed to understand hurricane genesis on Earth to three-dimensional climate models of ocean-covered exoplanets orbiting M dwarf stars. We find that hurricane genesis is most favorable on intermediate-rotating tidally locked terrestrial exoplanets with rotation periods of ∼8–10 days. As a result, hurricane genesis is most favorable for terrestrial exoplanets in the habitable zones of late-type M dwarf stars. The peak in the favorability of hurricane genesis at intermediate rotation occurs because sufficient spin is required for hurricane genesis, but the vertical wind shear on fast-rotating terrestrial exoplanets disrupts hurricane genesis. We find that hurricane genesis is less favorable on slowly rotating terrestrial exoplanets, which agrees with previous work. Future work using simulations that resolve hurricane genesis and evolution can test our expectations for how the environment affects the favorability of hurricane genesis on tidally locked terrestrial exoplanets.
The Hα Emission Line Variations of HR 6819
Authors: Gies Douglas R. , Wang 王 Luqian 璐茜
Published: July 2020

The star system HR 6819 was recently proposed by Rivinius et al. as the site of the nearest example of a stellar-mass black hole. Their spectra show evidence of two components: a B3 III star in a 40 day orbit and a stationary B-emission line star. Based upon the orbital mass function and the lack of evidence of a spectral component with reflex orbital motion, Rivinius et al. suggested that HR 6819 is a triple system consisting of an inner B3 III star plus black hole binary orbited by a distant Be star. Here we present an alternative model based upon an examination of the Hα emission line in their spectra. We show that the emission line displays the small reflex motion expected for the companion in the inner orbit and shows variations in profile shape related to orbital phase. This indicates that HR 6819 is a binary system consisting of a massive Be star and a low-mass companion that is the stripped down remnant of a former mass donor star in a mass transfer binary.

Composed of shocked solar wind, the Earth’s magnetosheath serves as a natural laboratory to study the transition of turbulence from low Alfvén Mach number, M
A, to high M
A. The simultaneous observations of magnetic field and plasma moments with unprecedented high temporal resolution provided by NASA’s Magnetospheric Multiscale Mission (MMS) enable us to study the magnetosheath turbulence at both magnetohydrodynamics (MHD) and sub-ion scales. Based on 1841 burst-mode segments of MMS-1 from 2015 September to 2019 June, comprehensive patterns of the spatial evolution of magnetosheath turbulence are obtained: (1) from the subsolar region to the flanks, M
A increases from <1 to >5. At MHD scales, the spectral indices of the magnetic-field and velocity spectra present a positive and negative correlation with M
A. However, no obvious correlations between the spectral indices and M
A are found at sub-ion scales. (2) From the bow shock to the magnetopause, the turbulent sonic Mach number,

, generally decreases from >0.4 to <0.1. All spectra steepen at MHD scales and flatten at sub-ion scales, representing positive/negative correlations with M
turb. The break frequency increases by 0.1 Hz when approaching the magnetopause for the magnetic-field and velocity spectra, while it remains at 0.3 Hz for the density spectra. (3) In spite of minor differences, similar results are found for the quasi-parallel and quasi-perpendicular magnetosheath. In addition, such spatial evolution of magnetosheath turbulence is found to be independent of the upstream solar wind conditions, e.g., the averaged Z-component of the interplanetary magnetic field and solar wind speed.
High-resolution Spectra for a Wide Range of Habitable Zone Planets around Sun-like Stars
Authors: Madden Jack , Kaltenegger Lisa
Published: July 2020

The search for life in the universe is currently focused on Earth-analog planets. However, we should be prepared to find a diversity of terrestrial exoplanets not only in terms of host star but also in terms of surface environment. Simulated high-resolution spectra of habitable planets covering a wide parameter space are essential in training retrieval tools, optimizing observing strategies, and interpreting upcoming observations. Ground-based extremely large telescopes like ELT, GMT, and TMT and future space-based mission concepts like Origins, HabEx, and LUVOIR are designed to have the capability of characterizing a variety of potentially habitable worlds. Some of these telescopes will use high-precision radial velocity techniques to obtain the required high-resolution spectra (R ≈ 100,000) needed to characterize potentially habitable exoplanets. Here we present a database of high-resolution (0.01 cm−1) reflection and emission spectra for simulated exoplanets with a wide range of surfaces, receiving similar irradiation as Earth around 12 different host stars from F0 to K7. Depending on surface type and host star, we show differences in spectral feature strength as well as overall reflectance, emission, and star-to-planet contrast ratio of terrestrial planets in the habitable zone of their host stars. Accounting for the wavelength-dependent interaction of the stellar flux and the surface will help identify the best targets for upcoming spectral observations in the visible and infrared. All of our spectra and model profiles are available online.
