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-γ-ray bursts, which are likely to be composed of a black hole and surrounding disk, therefore could be constrained by GW observation.
