Three-dimensional Core-Collapse Supernova Simulations: From shell burning to shock revival
Haakon Andresen, Evan P. O'Connor, C. E. Fields +1
The outcome of core-collapse supernova simulations depends sensitively on the multi-dimensional structure of the progenitor star at the onset of collapse. We perform three-dimensio…
Phoebus: Performance Portable GRRMHD for Relativistic Astrophysics
Brandon Barker, Mariam Gogilashvili, Janiris Rodriguez-Bueno +6
We introduce the open source code PHOEBUS (phifty one ergs blows up a star) for astrophysical general relativistic radiation magnetohydrodynamic simulations. PHOEBUS is designed fo…
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…
