An axisymmetric shock breakout indicated by prompt polarized emission from the type II supernova 2024ggi
Yi Yang, Xudong Wen, Lifan Wang +18
The death of massive stars is triggered by an infall-induced bounce shock that disrupts the star. How such a shock is launched and propagates through the star is a decade-long puzz…
Conversion and Damping of Nonaxisymmetric Internal Gravity Waves in Magnetized Stellar Cores
Cy S. David, Daniel Lecoanet, Pascale Garaud
Magnetism is thought to play an important role in the evolution and dynamics of stars, though little is known about magnetic fields deep within stellar interiors. A promising avenu…
Diversity of Cold Worlds: Predicted Near- to Mid-infrared Spectral Signatures of a Cold Brown Dwarf with Potential Auroral Heating

Recent JWST/NIRSpec observations have revealed strong methane emission at 3.326 microns in the 482 K brown dwarf CWISEP J193518.59154620.3 (W1935). Atmospheric modeling…
Apache Point Observatory follow-up of ACcelerating Candidate ExopLanet host Stars (APO ACCELS): Ages for 166 Accelerating Stars in the Northern Hemisphere
Anne E. Peck, Eric L. Nielsen, Robert J. De Rosa +14
Directly imaged substellar companions with well-constrained ages and masses serve as vital empirical benchmarks for planet formation and evolution models. Potential benchmark compa…

We present a high signal-to-noise (SNR 450), high-dispersion () H- and K-band spectroscopic atlas of the L7.5 and T0.5 components of the Luhman 1…
Carbon Stars From Gaia DR3 and the Space Density of Dwarf Carbon Stars
Benjamin R. Roulston, Naunet Leonhardes-Barboza, Paul J. Green +1
Carbon stars (with atmospheric C/O) range widely in temperature and luminosity, from low mass dwarfs to asymptotic giant branch stars (AGB). The main sequence dwarf carbon (dC)…
The cool brown dwarf Gliese 229 B is a close binary
Jerry W. Xuan, A. Mérand, W. Thompson +76
Owing to their similarities with giant exoplanets, brown dwarf companions of stars provide insights into the fundamental processes of planet formation and evolution. From their orb…
