Periodic Eruptive Variability of the Isolated Pre-main-sequence Star V347 Aurigae
Authors: Dahm S. E. , Hillenbrand L. A. 
Published: November 2020

Abstract
V347 Aurigae is associated with the small dark cloud L1438 and appears to be an isolated pre-main-sequence star located at distance d ≈ 200 pc. Multi-epoch, archival photometry reveals periodic brightness variations with amplitude V ≈ 2.0 mag occurring on timescales of ∼160 days that have persisted for decades. Regular-cadence, optical imaging of the source with the Zwicky Transient Facility shows that a small reflection nebula illuminated by V347 Aur also fluctuates in brightness, at times fading completely. Multi-epoch, Keck/HIRES data suggests the presence of two distinct spectral components: a prominent emission-line-dominated spectrum with a heavily veiled continuum correlated with the bright photometric state, and an M-type absorption line spectrum associated with quiescence. All spectra exhibit strong Balmer and He i line emission, consistent with accretion, as well as high velocity emission arising from the forbidden transitions of [O i], [N ii], and [S ii] that are generally associated with collimated jets and disk winds. There is no evidence in existing high-dispersion spectroscopy or high-resolution imaging for binarity of V347 Aur. The repeating outburst events are possibly linked to accretion instabilities induced by an undetected companion or a structure within the circumstellar disk that periodically increases the mass accretion rate. V347 Aur is perhaps analogous to an EXor-type variable, though more regularly recurring.
Untangling the Galaxy. II. Structure within 3 kpc

Published: November 2020

Abstract
We present the results of the hierarchical clustering analysis of the Gaia DR2 data to search for clusters, comoving groups, and other stellar structures. The current paper builds on the sample from the previous work, extending it in distance from 1 to 3 kpc and increasing the number of identified structures up to 8292. To aid in the analysis of the population properties, we developed a neural network called Auriga to robustly estimate the age, extinction, and distance of a stellar group based on the input photometry and parallaxes of the individual members. We apply Auriga to derive the properties of not only the structures found in this paper, but also previously identified open clusters. Through this work, we examine the temporal structure of the spiral arms. Specifically, we find that the Sagittarius Arm has moved by >500 pc in the last 100 Myr and the Perseus Arm has been experiencing a relative lull in star formation activity over the last 25 Myr. We confirm the findings of the previous paper on the transient nature of the spiral arms, with the timescale of transition of a few 100 Myr. Finally, we find a peculiar ∼1 Gyr old stream of stars that appears to be heliocentric. Its origin is unclear.
The Role of Parametric Instabilities in Turbulence Generation and Proton Heating: Hybrid Simulations of Parallel-propagating Alfvén Waves
Authors: González C. A. , Tenerani A. , Velli M. , Hellinger P. 
Published: November 2020

Abstract
Large-amplitude Alfvén waves tend to be unstable to parametric instabilities that result in a decay process of the initial wave into different daughter waves depending upon the amplitude of the fluctuations and the plasma beta. The propagation angle with respect to the mean magnetic field of the daughter waves plays an important role in determining the type of decay. In this paper, we revisit this problem by means of multidimensional hybrid simulations. In particular, we study the decay and the subsequent nonlinear evolution of large-amplitude Alfvén waves by investigating the saturation mechanism of the instability and its final nonlinear state reached for different wave amplitudes and plasma beta conditions. As opposed to one-dimensional simulations where the Decay instability is suppressed for increasing plasma beta values, we find that the decay process in multidimensions persists at large values of the plasma beta via the filamentation/magnetosonic decay instabilities. In general, the decay process acts as a trigger both to develop a perpendicular turbulent cascade and to enhance mean field-aligned wave–particle interactions. We find indeed that the saturated state is characterized by a turbulent plasma displaying a field-aligned beam at the Alfvén speed and increased temperatures that we ascribe to the Landau resonance and pitch-angle scattering in phase space.

Abstract
We present

SOFIA–FORCAST images of 14 intermediate-mass protostar candidates as part of the SOFIA Massive (SOMA) Star Formation Survey. We build spectral energy distributions, also using archival Spitzer, Herschel, and IRAS data. We then fit the spectral energy distributions with radiative transfer models of Zhang & Tan, based on turbulent core accretion theory, to estimate key protostellar properties. With the addition of these intermediate-mass sources, based on average properties derived from SED fitting, SOMA protostars span luminosities from

We have also considered about 50 protostars identified in infrared dark clouds that are expected to be at the earliest stages of their evolution. With this global sample, most of the evolutionary stages of high- and intermediate-mass protostars are probed. The best-fitting models show no evidence that a threshold value of the protocluster clump mass surface density is required to form protostars up to

FLEET: A Redshift-agnostic Machine Learning Pipeline to Rapidly Identify Hydrogen-poor Superluminous Supernovae
Authors: Gomez Sebastian , Berger Edo , Blanchard Peter K. , Hosseinzadeh Griffin , Nicholl Matt , Villar V. Ashley , Yin Yao 
Published: November 2020

Abstract
Over the past decade wide-field optical time-domain surveys have increased the discovery rate of transients to the point that ≲10% are being spectroscopically classified. Despite this, these surveys have enabled the discovery of new and rare types of transients, most notably the class of hydrogen-poor superluminous supernovae (SLSN-I), with about 150 events confirmed to date. Here we present a machine-learning classification algorithm targeted at rapid identification of a pure sample of SLSN-I to enable spectroscopic and multiwavelength follow-up. This algorithm is part of the Finding Luminous and Exotic Extragalactic Transients (FLEET) observational strategy. It utilizes both light-curve and contextual information, but without the need for a redshift, to assign each newly discovered transient a probability of being a SLSN-I. This classifier can achieve a maximum purity of about 85% (with 20% completeness) when observing a selection of SLSN-I candidates. Additionally, we present two alternative classifiers that use either redshifts or complete light curves and can achieve an even higher purity and completeness. At the current discovery rate, the FLEET algorithm can provide about 20 SLSN-I candidates per year for spectroscopic follow-up with 85% purity; with the Legacy Survey of Space and Time we anticipate this will rise to more than

events per year.
Measuring Stellar and Black Hole Masses of Tidal Disruption Events
Authors: Ryu Taeho , Krolik Julian , Piran Tsvi 
Published: November 2020

Abstract
The flare produced when a star is tidally disrupted by a supermassive black hole holds potential as a diagnostic of both the black hole mass and the star mass. We propose a new method to realize this potential based upon a physical model of optical/UV light production in which shocks near the apocenters of debris orbits dissipate orbital energy, which is then radiated from that region. Measurement of the optical/UV luminosity and color temperature at the peak of the flare leads directly to the two masses. The black hole mass depends mostly on the temperature observed at peak luminosity, while the mass of the disrupted star depends mostly on the peak luminosity. We introduce TDEmass, a method to infer the black hole and stellar masses given these two input quantities. Using TDEmass, we find, for 21 well-measured events, black hole masses between 5 × 105 and 107
M
⊙ and disrupted stars with initial masses between 0.6 and 13 M
⊙. An open-source python-based tool for TDEmass is available at https://github.com/taehoryu/TDEmass.git.

Abstract
We report on a detailed study of the mode switching in pulsar J1326−6700 by analyzing the data acquired from the Parkes 64 m radio telescope at 1369 MHz. During the abnormal mode, the emission at the central and trailing components becomes extremely weak. Meanwhile, the leading emission shifts toward earlier longitude by almost 2°, and remains in this position for typically less than a minute. The mean flux density of the normal mode is almost five times that of the abnormal mode. Our data show that, for PSR J1326−6700, 85% of the time was spent in the normal mode and 15% was in the abnormal mode. The intrinsic distributions of mode timescales can be well described by Weibull distributions, which present a certain amount of memory in mode switching. Furthermore, a quasiperiodicity has been identified in the mode switching in pulsar J1326−6700. The estimated delay emission heights based on the kinematical effects indicate that the abnormal mode may have originated from higher altitude than the normal mode.
On the X-Ray Properties of the Putative Central Compact Object in 1E 0102.2−7219
Authors: Long Xi , Gaetz Terrance J. , Plucinsky Paul P. 
Published: November 2020

Abstract
We have analyzed the archival Chandra X-ray Observatory observations of the compact feature in the Small Magellanic Cloud supernova remnant 1E 0102.2−7219, which has recently been suggested to be the central compact object remaining after the supernova explosion. In our analysis, we have used appropriate, time-dependent responses for each of the archival observations, have modeled the background instead of subtracting it, and have fit unbinned spectra to preserve the maximal spectral information. The spectrum of this feature is similar to the spectrum of the surrounding regions that have significantly enhanced abundances of O, Ne, and Mg. We find that the previously suggested blackbody model is inconsistent with the data, as Monte Carlo simulations indicate that more than 99% of the simulated data sets have a test statistic value lower than that of the data. The spectrum is described adequately by a nonequilibrium ionization thermal model with two classes of models that fit the data equally well. One class of models has a temperature of kT ∼ 0.79 keV, an ionization timescale of ∼3 × 1011 cm−3 s, and marginal evidence for enhanced abundances of O and Ne, and the other has a temperature of kT ∼ 0.91 keV, an ionization timescale of ∼7 × 1010 cm−3 s, and abundances consistent with local interstellar medium values. We also performed an image analysis and find that the spatial distribution of the counts is not consistent with that of a point source. The hypothesis of a point-source distribution can be rejected at the 99.9% confidence level. Therefore, this compact feature is most likely a knot of O- and Ne-rich ejecta associated with the reverse shock.

Abstract
We present a comprehensive catalog of the dippers—young stellar objects that exhibit episodic dimming—derived from one year’s worth of data of the Transiting Exoplanet Survey Satellite (TESS) full-frame images. In the survey, we found 35 dippers using the convolutional neural network, most of them newly discovered. Although these dippers are widely distributed over the first half-hemisphere that TESS surveyed, we identified the majority’s membership with the nearest association Scorpius–Centaurus, Velorum OB2, and the nearby Orion molecular cloud complex. However, several dippers are likely to be located in the field. We also found three old dippers whose age exceeds 10 million years, which is considered to be the disk dissipation time. The color–color diagram indicates that these old dippers are likely to have an extreme debris disk. In particular, we found a runaway old dipper having a large three-dimensional velocity of 72 km s−1. The dippers in the field, which were probably escaping from their birth molecular clouds or were born outside the current area of star-forming regions, are more common than previously considered.

Introduction: Antiretroviral therapy (ART) is an effective preventive strategy against tuberculosis (TB) in people living with HIV (PLWH). In Kazakhstan, according to the revised HIV treatment guideline (2017), ART should be initiated immediately after HIV diagnosis established, regardless of CD4+ count.
Aim: To evaluate the impact of early initiation of ART on TB infection in PLWH registered in the Center of Prevention and Control of AIDS, Almaty, Kazakhstan, between 2008 and 2018.
Methodology: A retrospective cohort study was conducted using the data of 4,053 patients from electronic HIV case management system (2008-2018) (EHCMS).
Results: The study revealed low rates (12.6%) of rapid ART (≤ 1 month after HIV diagnosis). Patients in the rapid ART initiation group were less likely to develop TB compared with those who started treatment >1 month after the HIV detection (odds ratio 1.6; 95% confidence interval [1.1, 2.2]; p = 0.00799). Interestingly, the risk for developing TB among patients receiving ART ≥ 1 month after HIV diagnosis was significantly higher compared with those not taking any treatment. The latter was explained by several confounding not addressed during the analysis, since ART was prescribed to patients with primarily deeper immunodeficiency, while the patients not receiving ART were less immunocompromised.
Conclusion: Despite the recently changed HIV treatment guideline in Kazakhstan, ART is still initiated based on the disease severity. In 2018, the initiation of ART during the first month after HIV diagnosis increased by 50%. However, it is necessary to reduce the time to initiation of ART for all patients.
Le carnet réflexif partagé : un espace d’écriture heuristique

Published: November 2020

La contribution analyse l’intérêt d’un outil de réflexivité pour l’enseignement tertiaire et la formation à l’enseignement : il s’agit de présenter ses tenants et aboutissants tout en donnant la parole à ses utilisateurs, des étudiants en formation à l’enseignement primaire ou secondaire, car ce sont elles et eux, in fine, qui sont le plus à même de donner à penser sur ce qui est en jeu dans l’écriture d’un carnet réflexif partagé (désormais CRP). L’analyse de leurs commentaires critiques permet d’appréhender l’adéquation ou la distorsion entre ce qui est souhaité et ce qui est vécu par ce corps estudiantin à travers un mode d’écriture heuristique et partagée. L’outil favorise à la fois une posture d’empathie et une posture de distanciation qui donne du sens à la réflexivité et à l’écriture.

Postmenopausal Alopecia due to Ovarian Hyperandrogenemia Treated with Bilateral Salpingo-oophorectomy
Authors: Acharya Santanu , Chakravorty Srirupa , Rae David 
Published: November 2020

ABSTRACT

Introduction
Increased ovarian production of androgens due to the stimulation of luteinizing hormone (LH) on theca cells can cause hyperandrogenism that may present with signs of alopecia in postmenopausal women.

Case description
A 65-year-old postmenopausal woman presented to the gynecology clinic with male-pattern baldness. Serum testosterone was high that was suppressed with gonadotropin-releasing hormone analog (GnRH agonist). This confirmed ovarian source of androgens. Laparoscopic salpingo-oophorectomy helped reduce androgen levels over a period of an year therefore reversing at least partially the hair loss.

Conclusion
Gonadotropin-releasing hormone analogs can be useful to diagnose the source of increased androgen levels to be of ovarian origin. Once confirmed, laparoscopic bilateral salpingo-oophorectomy can reverse hair loss in these cases.

A Case Series of Fibroids with Atypical Clinical Presentation: A Diagnostic Dilemma
Authors: Singh Pooja , Gupta Manjari 
Published: November 2020

ABSTRACT
Fibroids are the most common tumors of the female reproductive system. It is impossible to determine their true incidence, although frequently quoted incidence of as high as 50% has been found in certain longitudinal studies. Typical leiomyoma is a firm nodular well-circumscribed structure arising from the myometrium. Some of these fibroids may be asymptomatic while the usual symptoms associated are heavy menstrual bleeding, dysmenorrhea, abdominal discomfort, and pressure symptoms. Fibroids can be easily diagnosed by ultrasonography and MRI. However, some cases of fibroids may present as a diagnostic dilemma due to their bizarre presentation and unusual ultrasounds and MRI reports. Here we report three cases of fibroids with atypical clinical features that resulted in difficulty in making diagnosis.

Published: November 2020

ABSTRACTAimTo compare the clinical and biochemical characteristics of obese and lean women with polycystic ovary syndrome (PCOS). To confirm the significance of body mass index (BMI) in classifying PCOS.Materials and methodsThis was a comparative cross-sectional study done at Assam Medical College Hospital, Dibrugarh, Assam, in 1 year. Women who attended the hospital diagnosed to have PCOS based on Rotterdam's criteria were divided into lean and obese with BMI cut-off of 23. Clinical, anthropometric, and biochemical characteristics of both were compared. Body fat percentage was calculated using Harpenden skinfold calipers, and based on it, the lean group was found to have a normal weight, and obese subgroup with body fat percentage more than the cut-off.ResultThere was a significant difference in age, hirsutism score, and family history of diabetes and PCOS between the groups. The systolic blood pressure, serum cholesterol, and serum low-density lipoprotein (S.LDL) were statistically higher in the obese group. The normal weight obese group had features of the lean group, except for hyperandrogenism.ConclusionThe lean and obese PCOS are two discrete groups. Obese patients have a more androgenic and atherogenic lipid profile, but both groups should be screened. Body mass index is the easily available method, but it has a chance of missing out on the normal weight obese PCOS.Clinical significanceFollow-up is needed in both the groups, and the normal weight obese group behaves as the lean PCOS group; hence, BMI can be continued to be used as the differentiating factor.How to cite this articlePillai SS, Phukan PK, Dihingia P.
