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…

Exogeological inferences from white dwarf pollutants: the impact of stellar physics
Andrew M. Buchan, Pier-Emmanuel Tremblay, Antoine Bédard +2
Many white dwarfs have accreted material from their own planetary systems. These objects can be used to infer the composition of exoplanetary material and identify evidence for key…

MESA Isochrones and Stellar Tracks (MIST) III. The White Dwarf Cooling Sequence
Evan B. Bauer, Aaron Dotter, Charlie Conroy +3
We present a substantial update to the MESA Isochrones and Stellar Tracks (MIST) library, extending the MIST model grids and isochrones down the white dwarf (WD) cooling sequence w…
