Searching for Massive Remnant Planetary System Hosts with White Dwarf Gaia XP Spectra
Lou Baya Ould Rouis, J. J. Hermes, Pierre Bergeron +5
Remnant planetary systems around massive white dwarfs () are intrinsically rare and remain poorly characterized. As the evolutionary endpoints of i…
An Ultramassive White Dwarf with a Likely Oxygen-Neon Core
Stefan M. Arseneau, J. J. Hermes, Vedant Chandra +4
The core composition of ultramassive white dwarfs remains an open question in stellar evolution. The carbon content of white dwarf cores is critical to their role as progenitors of…
Constraints on White Dwarf Hydrogen Layer Masses Using Gravitational Redshifts
Stefan M. Arseneau, J. J. Hermes, Maria E. Camisassa +2
The hydrogen envelope is the outermost layer of a DA white dwarf; it makes up the entirety of the stellar photosphere, and yet its typical extent is difficult to model theoreticall…
Double White Dwarf Binaries in SDSS-V DR19 : A catalog of DA white dwarf binaries and constraints on the binary population
Gautham Adamane Pallathadka, Vedant Chandra, Nadia L. Zakamska +17
The fifth-generation Sloan Digital Sky Survey (SDSS-V) includes the first large-scale spectroscopic survey of white dwarfs (WDs) in the era of Gaia parallaxes. SDSS-V collects mult…
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…
