Testing White Dwarf Age Estimates using Wide Double White Dwarf Binaries from Gaia EDR3
Tyler M. Heintz, J. J. Hermes, Kareem El-Badry +4
White dwarf (WD) stars evolve simply and predictably, making them reliable age indicators. However, self-consistent validation of the methods for determining WD total ages has yet…
The Three-Dimensional Collapse of a Rapidly Rotating 16 Star
C. E. Fields
We report on the three-dimensional (3D) hydrodynamic evolution to iron core-collapse of a rapidly rotating 16 star. For the first time, we follow the 3D evolution of th…
Three-Dimensional Hydrodynamic Simulations of Convective Nuclear Burning In Massive Stars Near Iron Core Collapse
C. E. Fields, S. M. Couch
Non-spherical structure in massive stars at the point of iron core collapse can have a qualitative impact on the properties of the ensuing core-collapse supernova explosions and th…
On The Impact Of 22Ne On The Pulsation Periods Of Carbon-Oxygen White Dwarfs With Helium Dominated Atmospheres
Morgan T. Chidester, F. X. Timmes, Josiah Schwab +6
We explore changes in the adiabatic low-order g-mode pulsation periods of 0.526, 0.560, and 0.729 M carbon-oxygen white dwarf models with helium-dominated envelopes due to…
On The Development of Multidimensional Progenitor Models For Core-collapse Supernovae
C. E. Fields, S. M. Couch
Multidimensional hydrodynamic simulations of shell convection in massive stars suggest the development of aspherical perturbations that may be amplified during iron core-collapse.…
The Impact of White Dwarf Luminosity Profiles on Oscillation Frequencies
F. X. Timmes, Richard H. D. Townsend, Evan B. Bauer +3
KIC 08626021 is a pulsating DB white dwarf of considerable recent interest, and first of its class to be extensively monitored by Kepler for its pulsation properties. Fitting the o…
