Resum

We elucidate the feature of gravitational waves from binary neutron stars 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-gamma-ray bursts, which are likely to be composed of a black hole and surrounding disk, therefore could be constrained by GW observations.
