Gravitational Waves from Long-Duration Simulations of the Dynamical Bar Instability

Astrophysics 2010-11-19 v2 General Relativity and Quantum Cosmology

Abstract

Compact astrophysical objects that rotate rapidly may encounter the dynamical ``bar instability.'' The bar-like deformation induced by this rotational instability causes the object to become a potentially strong source of gravitational radiation. We have carried out a set of long-duration simulations of the bar instability with two Eulerian hydrodynamics codes. Our results indicate that the remnant of this instability is a persistent bar-like structure that emits a long-lived gravitational radiation signal.
