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…
The Impact of Nuclear Reaction Rate Uncertainties On The Evolution of Core-Collapse Supernova Progenitors
C. E. Fields, F. X. Timmes, R. Farmer +3
We explore properties of core-collapse supernova progenitors with respect to the composite uncertainties in the thermonuclear reaction rates by coupling the reaction rate probabili…
On Variations Of Pre-Supernova Model Properties
R. Farmer, C. E. Fields, I. Petermann +4
We explore the variation in single star 15-30 , non-rotating, solar metallicity, pre-supernova MESA models due to changes in the number of isotopes in a fully-coupl…
Properties of Carbon-Oxygen White Dwarfs From Monte Carlo Stellar Models
C. E. Fields, R. Farmer, I. Petermann +2
We investigate properties of carbon-oxygen white dwarfs with respect to the composite uncertainties in the reaction rates using the stellar evolution toolkit, Modules for Experimen…
On Carbon Burning in Super Asymptotic Giant Branch Stars
R. Farmer, C. E. Fields, F. X. Timmes
We explore the detailed and broad properties of carbon burning in Super Asymptotic Giant Branch (SAGB) stars with 2755 MESA stellar evolution models. The location of first carbon i…
