Research Abstract

Numerical-relativity simulations for the coalescence of binary neutron stars and black hole-neutron star binaries were performed for a wide variety of neutron star’s equations of state, for a wide range of masses of neutron stars and black holes, and fora wide range of black hole spins. We quantitatively and systematically clarified the merger process of these binaries, the product formed after the merger, and gravitational waves emitted. In particular, we clarified that gravitational waves in the merger phase depend strongly on the equations of state of neutron stars and black hole spins. This implies that they will be able to be constrained by the detection of gravitational waves which will be achieved in the near future by gravitational-wave detectors.
