Gravitational Waves from Core-Collapse Supernova using CHIMERA: Models and Numerical Methods

ORAL

Abstract

CHIMERA is a multi-dimensional code composed of three tightly coupled physics modules: VH1 used to evolve stellar gas hydrodynamics, MGFLD-TRANS which handles the neutrino transport, and XNET that describes the thermonuclear reactions. These are complemented with a sophisticated equation of state for nuclear matter (Lattimer-Swesty) and a self-gravity solver capable of an approximation to general-relativistic gravity. We will present the latest simulations of core-collapse supernova for different-mass progenitors. These models are evolved for up to one second in all cases, making them some of longest term simulations of their kind.
