Iron-rich Metal-poor Stars and the Astrophysics of Thermonuclear Events Observationally Classified as Type Ia Supernovae. I. Establishing the Connection
Authors: Reggiani Henrique , Schlaufman Kevin C. , Casey Andrew R. 
Published: August 2023

Abstract
The progenitor systems and explosion mechanisms responsible for the thermonuclear events observationally classified as Type Ia supernovae are uncertain and difficult to uniquely constrain using traditional observations of Type Ia supernova host galaxies, progenitors, light curves, and remnants. For the subset of thermonuclear events that are prolific producers of iron, we use published theoretical nucleosynthetic yields to identify a set of elemental abundance ratios infrequently observed in metal-poor stars but shared across a range of progenitor systems and explosion mechanisms: [Na, Mg, Co/Fe] < 0. We label stars with this abundance signature “iron-rich metal-poor,” or IRMP stars. We suggest that IRMP stars formed in environments dominated by thermonuclear nucleosynthesis and consequently that their elemental abundances can be used to constrain both the progenitor systems and explosion mechanisms responsible for thermonuclear explosions. We identify three IRMP stars in the literature and homogeneously infer their elemental abundances. We find that the elemental abundances of BD +80 245, HE 0533–5340, and SMSS J034249.53–284216.0 are best explained by the (double) detonations of sub-Chandrasekhar-mass CO white dwarfs. If our interpretation of IRMP stars is accurate, then they should be very rare in globular clusters and more common in the Magellanic Clouds and dwarf spheroidal galaxies than in the Milky Way’s halo. We propose that future studies of IRMP stars will quantify the relative occurrences of different thermonuclear event progenitor systems and explosion mechanisms.
Is There an Earth-like Planet in the Distant Kuiper Belt?
Authors: Lykawka Patryk Sofia , Ito 伊藤 Takashi 孝士 
Published: August 2023

Abstract
The orbits of trans-Neptunian objects (TNOs) can indicate the existence of an undiscovered planet in the outer solar system. Here we used N-body computer simulations to investigate the effects of a hypothetical Kuiper Belt planet (KBP) on the orbital structure of TNOs in the distant Kuiper Belt beyond ∼50 au. We used observations to constrain model results, including the well-characterized Outer Solar System Origins Survey (OSSOS). We determined that an Earth-like planet (m ∼ 1.5–3 M
⊕) located on a distant (semimajor axis a ∼ 250–500 au, perihelion q ∼ 200 au) and inclined (i ∼ 30°) orbit can explain three fundamental properties of the distant Kuiper Belt: a prominent population of TNOs with orbits beyond Neptune’s gravitational influence (i.e., detached objects with q > 40 au), a significant population of high-i objects (i > 45°), and the existence of some extreme objects with peculiar orbits (e.g., Sedna). Furthermore, the proposed KBP is compatible with the existence of identified gigayear-stable TNOs in the 2:1, 5:2, 3:1, 4:1, 5:1, and 6:1 Neptunian mean motion resonances. These stable populations are often neglected in other studies. We predict the existence of an Earth-like planet and several TNOs on peculiar orbits in the outer solar system, which can serve as observationally testable signatures of the putative planet’s perturbations.
Feasibility of Correlated Extensive Air Shower Detection with a Distributed Cosmic-Ray Network
Authors: Albin Eric K. , Whiteson Daniel 
Published: August 2023

Abstract
We explore the sensitivity offered by a global network of cosmic-ray detectors to a novel, unobserved phenomenon: widely separated simultaneous extended air showers. Existing localized observatories work independently to observe individual showers, offering insight into the source and nature of ultrahigh-energy cosmic rays. However no current observatory is large enough to provide sensitivity to anticipated processes such as the Gerasimova–Zatsepin effect or potential new physics that generate simultaneous air showers separated by hundreds to thousands of kilometers. A global network of consumer electronics (the Cosmic Rays Found In Smartphones (CRAYFIS) experiment), may provide a novel opportunity for observation of such phenomena. Two user scenarios are explored. In the first, with maximal user adoption, we find that statistically significant discoveries of spatially separated but coincident showers are possible within a couple years. In the second, more practical adoption model with 106 active devices, we find a worldwide CRAYFIS to be sensitive to novel “burst” phenomena where many simultaneous extensive air showers (EAS) occur at once.

Abstract
Previous Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) longslit observations of Eta Carinae (η Car) identified numerous absorption features in both the stellar spectrum, and in the adjacent nebular spectra, along our line of sight (LOS). The absorption features became temporarily stronger when the ionizing far-ultraviolet radiation field was reduced by the periastron passage of the secondary star. Subsequently, dissipation of a dusty structure in our LOS has led to a long-term increase in the apparent brightness of η Car, an increase in the ionizing ultraviolet (UV) radiation, and the disappearance of absorption from multiple velocity-separated shells extending across the foreground Homunculus lobe. We use HST/STIS spectro-images, coupled with published infrared and radio observations, to locate this intervening dusty structure. The velocity and spatial information indicate the occulter is ≈1000 au in front of η Car. The Homunculus is a transient structure composed of dusty, partially ionized ejecta that eventually will disappear due to the relentless rain of ionizing radiation and wind from the current binary system along with dissipation and mixing with the interstellar medium. This evolving complex continues to provide an astrophysical laboratory that changes on human timescales.
What Sets the Star Formation Rate of Molecular Clouds? The Density Distribution as a Fingerprint of Compression and Expansion Rates
Authors: Appel Sabrina M. , Burkhart Blakesley , Semenov Vadim A. , Federrath Christoph , Rosen Anna L. , Tan Jonathan C. 
Published: August 2023

Abstract
We use a suite of 3D simulations of star-forming molecular clouds, with and without stellar feedback, magnetic fields, and driven turbulence, to study the compression and expansion rates of the gas as functions of density. We show that, around the mean density, supersonic turbulence promotes rough equilibrium between the amounts of compressing and expanding gas, consistent with continuous gas cycling between high- and low-density states. We find that the inclusion of protostellar jets produces rapidly expanding and compressing low-density gas. We find that the gas mass flux peaks at the transition between the lognormal and power-law forms of the density probability distribution function (PDF). This is consistent with the transition density tracking the post-shock density, which promotes an enhancement of mass at this density (i.e., shock compression and filament formation). At high densities, the gas dynamics are dominated by self-gravity: the compression rate in all of our runs matches the rate of the run with only gravity, suggesting that processes other than self-gravity have little effect at these densities. The net gas mass flux becomes constant at a density below the sink formation threshold, where it equals the star formation rate. The density at which the net gas mass flux equals the star formation rate is one order of magnitude lower than our sink threshold density, corresponds to the formation of the second power-law tail in the density PDF, and sets the overall star formation rates of these simulations.

Abstract
Recent observations with the Imaging X-ray Polarimetry Explorer (IXPE) of two anomalous X-ray pulsars provided evidence that X-ray emission from magnetar sources is strongly polarized. Here we report on the joint IXPE and XMM-Newton observations of the soft γ-repeater SGR 1806–20. The spectral and timing properties of SGR 1806–20 derived from XMM-Newton data are in broad agreement with previous measurements; however, we found the source at an all-time low persistent flux level. No significant polarization was measured apart from the 4–5 keV energy range, where a probable detection with PD = 31.6% ± 10.5% and

was obtained. The resulting polarization signal, together with the upper limits we derive at lower and higher energies (2–4 and 5–8 keV, respectively), is compatible with a picture in which thermal radiation from the condensed star surface is reprocessed by resonant Compton scattering in the magnetosphere, similar to what was proposed for the bright magnetar 4U 0142+61.
The Spatial Distribution of the Unidentified 2.07 μm Absorption Feature on Europa and Implications for its Origin
Authors: Davis M. Ryleigh , Brown Michael E. , Trumbo Samantha K. 
Published: August 2023

Abstract
A weak absorption feature at 2.07 μm on Europa’s trailing hemisphere has been suggested to arise from radiolytic processing of an endogenic salt, possibly sourced from the interior ocean. However, if the genesis of this feature requires endogenic material to be present, one might expect to find a correlation between its spatial distribution and the recently disrupted chaos terrains. Using archived near-infrared observations from the Very Large Telescope/SINFONI with a ∼1 nm spectral resolution and a linear spatial resolution ∼130 km, we examine the spatial distribution of this feature in an effort to explore this endogenic formation hypothesis. We find that, while the presence of the 2.07 μm feature is strongly associated with the irradiation pattern on Europa’s trailing hemisphere, there is no apparent association between the presence or depth of the absorption feature and Europa’s large-scale chaos terrain. This spatial distribution suggests that the formation pathway of the 2.07 μm feature on Europa is independent of any endogenous salts within the recent geology. Instead, we propose that the source of this feature may simply be a product of the radiolytic sulfur cycle or arise from some unidentified parallel irradiation process. Notably, the 2.07 μm absorption band is absent from the Pwyll crater ejecta blanket, suggesting that radiolytic processing has not had enough time to form the species responsible and placing a lower limit on the irradiation timescale. We are unable to find a plausible spectral match to the 2.07 μm feature within the available laboratory data.
A Curious Case of Acute STEMI in a Young Patient; Things are Not Always What They Seem

Published: August 2023

BACKGROUND: Acute myocardial infarction (MI) is a rare occurrence in patients under 40 years of age without positive family history for coronary artery disease (CAD). Genetic conditions as inherited thrombophilia can lead to a hypercoagulable state, resulting in thromboembolic events and arterial thrombosis.
CASE SUMMARY: We present a case of a 35-year-old male patient who presented to the emergency room with an inferior MI after a strenuous cycling exercise. An urgent coronary angiography showed thrombotic formations in the right coronary artery without atherosclerotic plaques. Plain old balloon angioplasty and thrombus aspiration were performed, which was followed by GP IIb/IIIa inhibitor infusion and unfractionated heparin for 24 h. From past medical history, the patient had COVID-19 like symptoms 20 days before the event and had his first dose of anti- COVID vaccine 2 weeks prior. After additional testing, molecular genetic analysis results revealed the patient to be heterozygous for factor V Leiden (FVL) and homozygous for methylenetetrahydrofolate reductase C677T gene mutation. The patient was discharged on direct oral anticoagulant and antiplatelet therapy. After 1-year follow-up, he had no symptoms or recurrent cardiovascular events.
CONCLUSION: Inherited thrombophilia is а significant risk factor for CAD and performing genetic testing in younger patients with a cardiovascular event and plays an important role for adequate treatment and prophylaxis from recurrent complications. The use of oral anticoagulation for prophylaxis is shown to be effective in these patients. However, further studies are needed to prove their exact role and duration of treatment.
Comment (vraiment) généraliser l’Éducation à la Vie Relationnelle, Affective et Sexuelle (EVRAS) à Bruxelles ?

Published: August 2023

La généralisation de l’éducation à la vie relationnelle, affective et sexuelle (EVRAS) est un projet mis en place depuis de nombreuses années en RBC francophone. Malgré la mobilisation de politiques, de nombreux acteurs et d’établissements scolaires, plus de dix ans ont été nécessaires après son intégration dans les missions de l’enseignement pour que l’EVRAS devienne obligatoire à la rentrée 2023, sous une forme minimale. L’absence d’un réel parcours EVRAS tout au long de la scolarité est problématique et participe aux inégalités sociales de santé déjà fortement présentes à Bruxelles. Cette étude participe à l’élan récemment impulsé par la COCOF et a pour objectif de contribuer à la définition de futures politiques publiques ambitieuses à ce sujet : elle propose trois scénarios de généralisation de l’EVRAS dans l’enseignement obligatoire bruxellois francophone, accompagné chacun d’une modélisation budgétaire.
