Probing Thin Winds in Massive OB Stars of the SMC with JWST/NIRSPEC Br-alpha Spectroscopy

Miriam Garcia, Alexander W. Fullerton, Francisco Najarro +12

Mass loss is a key physical process in the evolution of massive stars, the impact of which propagates into galactic evolution, population synthesis models, the interpretation of hi…

Resolution-Corrected White Dwarf Gravitational Redshifts Validate SDSS-V Wavelength Calibration and Enable Accurate Mass-Radius Tests

Stefan M. Arseneau, J. J. Hermes, Nadia L. Zakamska +7

Leveraging the large sample size of low-resolution spectroscopic surveys to constrain white dwarf stellar structure requires an accurate understanding of the shapes of hydrogen abs…

A Large Catalog of DA White Dwarf Characteristics Using SDSS and Gaia Observations

Nicole R. Crumpler, Vedant Chandra, Nadia L. Zakamska +12

We present a catalog of 8545 and 19,257 unique DA white dwarfs observed in SDSS Data Release 19 and previous SDSS data releases, respectively. This is the largest catalog of both s…

Radiative-transfer models for dusty Type II supernovae

Luc Dessart, D. John Hillier, Arkaprabha Sarangi

Dust is expected to form on a year timescale in core-collapse supernova (SN) ejecta. Its existence is revealed through an infrared brightening, an optical dimming, or a blue-red em…

X-Shooting ULLYSES: massive stars at low metallicity: XII. The clumped winds of O-type (super)giants in the Large Magellanic Cloud

Sarah A. Brands, Frank Backs, Alex de Koter +23

Mass loss governs the evolution of massive stars and shapes the stellar surroundings. To quantify the impact of the stellar winds we need to know the exact mass-loss rates; however…

The Progenitor Systems of Classical Novae in M31

C. S. Abelson, Carles Badenes, Laura Chomiuk +4

We present the first characterization of the statistical relationship between a large sample of novae in M31 and their progenitor stellar populations in the form of a delay time di…
