Core Collapse Supernovae using CHIMERA: Gravitational Radiation from Non-Rotating Progenitors

TL;DR

This paper presents preliminary gravitational wave signatures from 2D simulations of core collapse supernovae with non-rotating progenitors, using the CHIMERA code, to aid detection efforts by observatories like LIGO.

Contribution

It provides the first detailed gravitational wave signals from non-rotating supernova models simulated with the CHIMERA code.

Findings

Simulations show detectable gravitational wave signals from non-rotating supernovae.

Explosions are followed for over half a second post-bounce.

Preliminary signatures can inform gravitational wave detection strategies.

Abstract

The CHIMERA code is a multi-dimensional multi-physics engine dedicated primarily to the simulation of core collapse supernova explosions. One of the most important aspects of these explosions is their capacity to produce gravitational radiation that is detectable by Earth-based laser-interferometric gravitational wave observatories such as LIGO and VIRGO. We present here preliminary gravitational signatures of two-dimensional models with non-rotating progenitors. These simulations exhibit explosions, which are followed for more than half a second after stellar core bounce.
