MHD Models of Stellar Core Collapse with GenASiS

Abstract

We present magnetohydrodynamic (MHD) models of stellar core collapse computed with our astrophysical MHD code GenASiS. Microphysics in the models include a realistic equation of state and a simple parametrization of deleptionization during collapse. We give a brief description of some numerical results, and discuss requirements for capturing the physics of the magnetorotational instability in the context of core collapse supernovae.
