Abstract:

We elucidate the feature of gravitaional 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.
