Abstract
Warm Jupiters are close-in giant planets with relatively large planet–star separations (i.e., 10 < a/R
⋆ < 100). Given their weak tidal interactions with their host stars, measurements of stellar obliquity may be used to probe the initial obliquity distribution and dynamical history for close-in gas giants. Using spectroscopic observations, we confirm the planetary nature of TOI-1859b and determine the stellar obliquity of TOI-1859 to be λ = 38.9

Published: July 2023

Abstract
We investigate the nucleosynthesis and kilonova properties of binary neutron star (NS) merger models that lead to intermediate remnant lifetimes of ∼0.1–1 s until black hole (BH) formation and describe all components of the material ejected during the dynamical merger phase, NS remnant evolution, and final viscous disintegration of the BH torus after gravitational collapse. To this end, we employ a combination of hydrodynamics, nucleosynthesis, and radiative transfer tools to achieve a consistent end-to-end modeling of the system and its observables. We adopt a novel version of the Shakura–Sunyaev scheme allowing the approximate turbulent viscosity inside the NS remnant to vary independently of the surrounding disk. We find that asymmetric progenitors lead to shorter remnant lifetimes and enhanced ejecta masses, although the viscosity affects the absolute values of these characteristics. The integrated production of lanthanides and heavier elements in such binary systems is subsolar, suggesting that the considered scenarios contribute in a subdominant fashion to r-process enrichment. One reason is that BH tori formed after delayed collapse exhibit less neutron-rich conditions than typically found, and often assumed in previous BH torus models, for early BH formation. The outflows in our models feature strong anisotropy as a result of the lanthanide-poor polar neutrino-driven wind pushing aside lanthanide-rich dynamical ejecta. Considering the complexity of the models, the estimated kilonova light curves show promising agreement with AT 2017gfo after times of several days, while the remaining inconsistencies at early times could possibly be overcome in binary configurations with a more dominant neutrino-driven wind relative to the dynamical ejecta.
The Kelvin–Helmholtz Instability at the Boundary of Relativistic Magnetized Jets
Authors: Chow Anthony , Davelaar Jordy , Rowan Michael E. , Sironi Lorenzo 
Published: July 2023

Abstract
We study the linear stability of a planar interface separating two fluids in relative motion, focusing on conditions appropriate for the boundaries of relativistic jets. The jet is magnetically dominated, whereas the ambient wind is gas-pressure-dominated. We derive the most general form of the dispersion relation and provide an analytical approximation of its solution for an ambient sound speed much smaller than the jet Alfvén speed v
A, as appropriate for realistic systems. The stability properties are chiefly determined by the angle ψ between the wavevector and the jet magnetic field. For ψ = π/2, magnetic tension plays no role, and our solution resembles the one of a gas-pressure-dominated jet. Here, only sub-Alfvénic jets are unstable (

Abstract
We present the analysis of two unusually red L dwarfs, CWISE J075554.14−325956.3 (W0755−3259) and CWISE J165909.91−351108.5 (W1659−3511), confirmed by their newly obtained near-infrared spectra collected with the TripleSpec4 spectrograph on the Southern Astrophysical Research Telescope. We classify W0755−3259 as an L7 very low-gravity dwarf, exhibiting extreme redness with a characteristic peaked H-band and spectral indices typical of low-gravity late-type L dwarfs. We classify W1659-3511 as a red L7 field-gravity dwarf, with a more rounded H-band peak and spectral indices that support a normal gravity designation. W1659−3511 is noticeably fainter than W0755−3259, and the rounded H-band of W1659−3511 may be evidence of CH4 absorption.
Heine, écrivain français putatif ?
Authors: Calvié Lucien 
Published: July 2023

Du vivant de Heine déjà et par la suite, sa réception française a posé et reposé le problème de sa « nationalité » littéraire : est-il un « écrivain français » ou un « poète allemand » ? La question est également sous-jacente aux deux grandes éditions critiques existantes, celles dites « de Düsseldorf » et « de Weimar ». Paradoxalement, et davantage même que la Germanistik en Allemagne, la germanistique française a longtemps paru privilégier, de diverses manières, un Heine « allemand » au détriment du Heine « français ». Peut-être est-il temps de rééquilbrer l’approche de Heine, par exemple autour de la notion, avancée par Heine lui-même à propos de l’un de ses textes, de « livre allemand en langue française ». Ces diverses considérations nous conduisent, concernant la caractérisation littéraire nationale de Heine, à proposer la notion d’« écrivain français putatif », parallèlement à sa pérennité comme « poète allemand ».
Langue croisée – Walter Benjamins Erinnerungsarbeit zwischen Hören und Sehen, Paris und Berlin
Authors: Kazmaier Daniel 
Published: July 2023

Le livre Une Enfance berlinoise autour de 1900 de Walter Benjamin fait apparaître un lien entre la part francophone et la part germanophone de l’auteur. Suite à la publication de l’ensemble des textes formant ce projet mémoriel, on dispose désormais d’une base solide pour étudier cet ensemble bilingue hétéroclite, composé de plusieurs versions, remaniements, compilations. Sur la base d’analyses poétologiques et d’une approche génétique, cet article retrace le travail de mémoire de Benjamin dans Une Enfance berlinoise. Ce travail mémoriel se rattache aux lieux que sont Paris et Berlin, entremêle la sensualité de l’ouïe et la vision pour reproduire un enchevêtrement dans la langue elle-même, en tant que langue croisée. Sur le plan philologique, cette étude reconstitue les transpositions effectuées par Walter Benjamin sous un triple aspect : le remaniement intervenu entre la première version berlinoise et la version parisienne, plus tardive ; une comparaison des textes Die Mummerehlen et Loggien ; enfin, le transfert d’un passage du texte Die Mummerehlen vers le texte français Peintures chinoises à la Bibliothèque nationale.
Targeting 2-Oxoglutarate–Dependent Dioxygenases Promotes Metabolic Reprogramming That Protects against Lethal SARS-CoV-2 Infection in the K18-hACE2 Transgenic Mouse Model

Abstract
Dysregulation of host metabolism is a feature of lethal SARS-CoV-2 infection. Perturbations in α-ketoglutarate levels can elicit metabolic reprogramming through 2-oxoglutarate–dependent dioxygenases (2-ODDGs), leading to stabilization of the transcription factor HIF-1α. HIF1-α activation has been reported to promote antiviral mechanisms against SARS-CoV-2 through direct regulation of ACE2 expression (a receptor required for viral entry). However, given the numerous pathways HIF-1α serves to regulate it is possible that there are other undefined metabolic mechanisms contributing to the pathogenesis of SARS-CoV-2 independent of ACE2 downregulation. In this study, we used in vitro and in vivo models in which HIF-1α modulation of ACE2 expression was negated, allowing for isolated characterization of the host metabolic response within SARS-CoV-2 disease pathogenesis. We demonstrated that SARS-CoV-2 infection limited stabilization of HIF-1α and associated mitochondrial metabolic reprogramming by maintaining activity of the 2-ODDG prolyl hydroxylases. Inhibition of 2-ODDGs with dimethyloxalylglycine promoted HIF-1α stabilization following SARS-CoV-2 infection, and significantly increased survival among SARS-CoV-2–infected mice compared with vehicle controls. However, unlike previous reports, the mechanism by which activation of HIF-1α responses contributed to survival was not through impairment of viral replication. Rather, dimethyloxalylglycine treatment facilitated direct effects on host metabolism including increased glycolysis and resolution of dysregulated pools of metabolites, which correlated with reduced morbidity. Taken together, these data identify (to our knowledge) a novel function of α-ketoglutarate–sensing platforms, including those responsible for HIF-1α stabilization, in the resolution of SARS-CoV-2 infection and support targeting these metabolic nodes as a viable therapeutic strategy to limit disease severity during infection.
