The Hottest Neptunes Orbit Metal-rich Stars
Authors: Vissapragada Shreyas , Behmard Aida 
Published: February 2025

Abstract
The Neptune desert is no longer empty. A handful of close-in planets with masses between those of Neptune and Saturn have now been discovered, and their puzzling properties have inspired a number of interesting theories on the formation and evolution of desert-dwellers. While some studies suggest that Neptune desert planets form and evolve similarly to longer-period Neptunes, others argue that they are products of rare collisions between smaller planets, or that they are the exposed interiors of giant planets (i.e., “hot Jupiters gone wrong”). These origin stories make different predictions for the metallicities of Neptune desert host stars. In this paper, we use the homogeneous catalog of stellar metallicities from Gaia Data Release 3 to investigate the origins of Neptune desert dwellers. We find that planets in the Neptune desert orbit stars that are significantly more metal rich than the hosts of longer-period Neptunes (p = 0.0016) and smaller planets (p = 0.00014). In contrast, Neptune desert host star metallicities are statistically indistinguishable from those of hot Jupiter host stars (p = 0.55). Therefore, we find it relatively unlikely that Neptune desert planets formed and evolved similarly to longer-period Neptunes, or that they resulted from collisions between smaller planets, at least without another metallicity-selective process involved. A more straightforward explanation for this result is that planets in the desert truly are the exposed interiors of larger planets. Atmospheric spectroscopy of Neptune desert worlds may therefore provide a rare glimpse into the interiors of giant exoplanets.

Abstract
Suspended dust is a vital component of Martian climatic system and its temporal-spatial variation can influence the recession of the South Polar Seasonal Cap (SPSC). However, dust activity varies across different stages and years, affecting the SPSC recession process differently. Continuous observations of SPSC/South Polar Residual Cap (SPRC) across several Martian years, alongside segmented analyses of annual dust activity, will provide new insights into the climate conditions of Martian south polar region. Here, we performed a combined analysis on the extents of SPSC from MY28-MY31 and MY36, together with the concurrent Martian atmospheric optical thickness, to assess the influence of dust activity at various recession time steps. Results show that dust activity peaks in both spring and summer can impact the SPSC/SPRC recession. The recession process is accelerated if the dust activity peak occurs earlier. If the timing of the peak dust activity is identical, the intensity of the dust activity influences the recession. Specific regions, such as the “Cryptic Region” and the Mountains of Mitchel, respond uniquely to dust activity. Higher dust intensity slows the recession of the Cryptic Region, while the SPSC in the Mountains of Mitchel area shows variability in recession timing based on local dust activity intensity. This research provides observational constraints that enhance our understanding of Martian atmospheric circulation and can potentially aid the future development of polar dust activity models.

Abstract
We explore the empirical power-law relationship between X-ray luminosity (L
X) and total surface magnetic flux (Φ), established across solar magnetic elements, time- and disk-averaged emission from the Sun, older active stars, and pre-main-sequence (PMS) stars. Previous models of large PMS X-ray flares, lacking direct magnetic field measurements, showed discrepancies from this baseline law, which MHD simulations attribute to unusually strong magnetic fields during flares. To test this, we used nearly simultaneous Chandra X-ray and HET-HPF near-infrared observations of four young Orion stars, measuring surface magnetic fields during or just after powerful PMS X-ray flares. We also modeled these PMS X-ray flares, incorporating their measured magnetic field strengths. Our findings reveal magnetic field strengths at the stellar surface typical of nonflaring PMS stars, ruling out the need for abnormally strong fields during flares. Both PMS and solar flares deviate from the L
X–Φ law, with PMS flares exhibiting a more pronounced deviation, primarily due to their much larger active regions on the surface and larger flaring loop volumes above the surface compared to their solar counterparts. These deviations likely stem from the fact that powerful flares are driven by magnetic reconnection, while baseline X-ray emission may involve less efficient mechanisms like Alfvén wave heating. Our results also indicate a preference for dipolar magnetic loops in PMS flares, consistent with Zeeman–Doppler imaging of fully convective stars. This requirement for giant dipolar loops aligns with MHD predictions of strong dipoles supported by polar magnetic surface active regions in fast-rotating, fully convective stars.
Relativistic Binary Precession: Impact on Eccentric Massive Binary Black Hole Accretion and Hydrodynamics

Published: February 2025

Abstract
Recent hydrodynamical simulations have shown that circumbinary gas disks drive the orbits of massive binary black holes (BHs) to become eccentric, even when general relativistic (GR) corrections to the orbit are significant. Here, we study the GR apsidal precession of eccentric equal-mass massive binary BHs in circumbinary disks via two-dimensional hydrodynamical simulations. We perform a suite of simulations comparing precessing and nonprecessing binaries across a range of eccentricities, semimajor axes, and precession rates. We find that the GR precession of the binary's semimajor axis can introduce a dominant modulation in the binary's accretion rate and the corresponding high-energy electromagnetic light curves. We discuss the conditions under which this occurs and its detailed characteristics and mechanism. Finally, we discuss the potential to observe these precession signatures in electromagnetic- and gravitational-wave observations, as well as the precession signal's unique importance as a potential tool to constrain the mass, eccentricity, and semimajor axis of binary merger events.
Black Hole Supernovae, Their Equation of State Dependence, and Ejecta Composition

Published: February 2025

Abstract
Recent literature on core-collapse supernovae suggests that a black hole (BH) can form within ∼1 s of shock revival, while still culminating in a successful supernova. We refer to these as BH supernovae, as they are distinct from other BH formation channels in both timescale and impact on the explosion. We simulate these events self-consistently from core collapse until 20–50 days after collapse using three axisymmetric models of a 60 M
⊙ zero-age main-sequence progenitor star and investigate how the composition of the ejecta is impacted by the BH formation. We employ Skyrme-type equations of state (EOSs) and vary the uncertain nucleonic effective mass, which affects the pressure inside the proto–neutron star through the thermal part of the EOS. This results in different BH formation times and explosion energies at BH formation, yielding final explosion energies between 0.06 and 0.72 × 1051 erg with 21.8–23.3 M
⊙ of ejecta, of which 0–0.018 M
⊙ is 56Ni. Compared to expectations from 1D simulations, we find more nuanced EOS dependences of the explosion dynamics, the mass of the BH remnant, and the elemental composition of the ejecta. We investigate why the explosions survive despite the massive overburden and link the shape of the diagnostic energy curve and character of the ejecta evolution to the progenitor structure.
Long-term Evolution of Sco X-1: Implications for the Current Spin Frequency and Ellipticity of the Neutron Star
Authors: Kar Abhijnan , Ojha Pulkit , Bhattacharyya Sudip 
Published: February 2025

Abstract
Sco X-1 is the brightest observed extrasolar X-ray source, which is a neutron star (NS) low-mass X-ray binary (LMXB) and is thought to have a strong potential for continuous gravitational waves (CW) detection due to its high accretion rate and relative proximity. Here, we compute the long-term evolution of its parameters, particularly the NS spin frequency (ν) and the surface magnetic field (B), to probe its nature and its potential for CW detection. We find that Sco X-1 is an unusually young (∼7 × 106 yr) LMXB and constrain the current NS mass to ∼1.4–1.6 M
⊙. Our computations reveal a rapid B decay, with the maximum current value of ∼1.8 × 108 G, which can be useful to constrain the decay models. Note that the maximum current ν value is ∼550 Hz, implying that, unlike what is generally believed, a CW emission is not required to explain the current source properties. However, ν will exceed an observed cutoff frequency of ∼730 Hz, and perhaps even the NS breakup frequency, in the future without a CW emission. The minimum NS mass quadrupole moment (Q) to avoid this is ∼(2–3) × 1037 g cm2, corresponding to a CW strain of ∼10−26. Our estimation of current ν values can improve the CW search sensitivity.
Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith
Authors: Bart Gwendolyn D. 
Published: February 2025

Abstract
Lunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons. The depth of the regolith is determined by the maximum depth reworked by impactors. Older surfaces are expected to have thicker regoliths because they have been exposed to longer periods of bombardment than younger surfaces—a concept I refer to as the Depth–Age Hypothesis. To test the hypothesis, I compare published, measured regolith depths on mare basalts with published, measured surface ages of those mare. If the Depth–Age Hypothesis is correct, older mare surfaces should have thicker regoliths than younger surfaces. Contrary to the hypothesis, published data show that both younger and older lunar surfaces have median regolith depths ranging from about 3 to 9 m. Possible reasons for this finding include variations among measurement methods, reporting regolith depths with too great precision, and the inherent variability of the lunar regolith.

We studied the diet composition and feeding preferences of the Grey Plover (Pluvialis squatarola) at its migration stopover at Pomorie Lake on the South-Western Black Sea coast, Bulgaria, through DNA metabarcoding of faeces.
Faecal samples were collected in autumn 2020 and spring 2021, preserved in 95% ethanol, and stored at -20ºC until DNA extraction and metabarcoding. Two molecular markers were initially targeted - ITS2 for plant identification, and CO1 for animal identification; however, the subsequent analyses focused on the dominant animal prey identified by CO1. Concurrently, coastal habitats where the birds were observed to feed, such as the surf zone and the sandy supralittoral shore, were also sampled to determine prey availability.
The Grey Plover had a broad diet spectrum, with 332 prey taxa in total identified by metabarcoding, belonging to 7 phyla, 14 classes, 24 orders, 78 families and 119 genera. The birds consumed both terrestrial and marine taxa, suggesting that multiple coastal habitats are used for foraging. Terrestrial arthropods, particularly insects, predominated in the diet, while mytilid bivalves were the most represented marine taxon.
The results suggest that at the studied migration stopover site at the SW Black Sea, the Grey Plover was a generalist feeder, which agrees with previous studies from different areas. Most birds fed on insects (Diptera, Lepidoptera, Hymenoptera); a few individuals also specialised on marine molluscs, arachnids and polychaetes. The most abundant potential prey in the environ­ment were not the most frequently consumed, possibly because the sampling methods were not suitable for the full spectrum of available prey (particularly the flying insects).
We found limited seasonal variation in Grey Plover diet composition and preferences, with the proportions of some prey taxa differing slightly between seasons, probably due to seasonal variations in their abundance and activity in coastal habitats.
Our results contribute to the knowledge of Grey Plover diet, prey choice and habitat use in a little-studied region on the Black Sea-Mediterranean Flyway. The new information could contribute towards designing effective conservation measures to preserve habitat quality at stopover sites for this wader and others with similar ecology, ensuring migration success at a time when migratory bird populations are increasingly threatened by habitat loss and degradation.
The results are presented and analysed in detail in Vassileva et al. (2024).

La conception de la corruption dans le droit pénal
Authors: Bouvier Laure-Alice 
Published: February 2025

Cet article passe en revue un certain nombre d’interrogations : comment le droit pénal appréhende-t-il la corruption qui touche la sphère publique ? A-t-il une approche uniforme du phénomène quels que soient les secteurs ou a-t-il une approche différente selon qu’il s’agit d’argent public ou d’argent privé ? Le droit pénal donne-t-il au juge les moyens de réprimer efficacement le phénomène ? Quelles sont les principales limites à cet égard ?

Premier bilan du prélèvement à la source après un semestre de mise en œuvre : une entrée en réforme réussie
Authors: Berthelot Grégory 
Published: February 2025

Le prélèvement à la source est une réforme de simplification du recouvrement de l’impôt sur le revenu, qui vise à en rendre le paiement contemporain de la perception des revenus correspondants. Afin d’éviter un double prélèvement en 2019, un dispositif spécifique a été prévu pour l’année de transition (« année blanche »). L’impôt sur les revenus non exceptionnels perçus en 2018 et situé dans le champ du prélèvement à la source a ainsi été effacé. Grâce à la forte mobilisation et à la bonne préparation des nombreux acteurs concernés, l’entrée en réforme s’est très bien passée, tant du point de vue des collecteurs que des usagers. À l’issue du premier semestre de mise en œuvre du prélèvement à la source, on peut donc dresser un bilan positif de la réforme, le prélèvement à la source étant désormais considéré comme un acquis par la grande majorité des contribuables.

L’impôt au Cameroun : entre territorialité, extra-territorialité et re-territorialité
Authors: Abeng Messi François 
Published: February 2025

Au Cameroun, l’impôt oscille entre deux fondements contradictoires : la territorialité et la déterritorialité. Si le premier est stabilisant, le second en revanche est mouvant, voire glissant. En effet, sous l’effet de la mondialisation, de la communication, voire de la décentralisation, la base imposable échappe de plus en plus à l’État détenteur de la souveraineté fiscale. C’est la raison pour laquelle qu’il est souhaité de changer de paradigme pour une reterritorialisation.
L’esprit de corps. Sur les ressorts imaginaires et affectifs du politique
Authors: Hervet Céline , Lantoine Jacques-Louis 
Published: February 2025

Ce dossier met au jour certains des enjeux philosophiques de la notion d’esprit de corps en adoptant successivement trois angles : celui de l’ambivalence d’un concept en apparence insaisissable, fantasmatique, voire magique, mais qui produit des effets d’identification et d’unification politiques puissants, celui d’une recontextualisation et d’une critique de la métaphore organiciste du « corps politique » où s’éprouve la teneur même du régime et de la société démocratiques, et enfin celui d’un retour à l’âge classique où sont mis au jour les ressorts affectifs et imaginatifs des liens sociaux, qu’il s’agisse des rapports de subordination ou des rapports de solidarité qui lient les membres d’un même groupe et assurent la cohésion de l’ordre social et politique.
