Abstract
We elucidate the feature of gravitational waves (GWs) from a binary-neutron-star merger collapsing to a black hole by general relativistic simulation. We show that GW spectrum imprints the coalescence dynamics, formation process of disk, equation of state for neutron stars, total masses, and mass ratio. A formation mechanism of the central engine of short--ray bursts, which are likely to be composed of a black hole and surrounding disk, therefore could be constrained by GW observation.

Precise simulations for future gravitational wave detectors
Published 5 April 2010
New simulations of merging binary neutron stars include details of the gravitational wave signature that should in coming years help us understand another mysterious process—short gamma-ray bursts.
