Coalescence of Black Hole-Neutron Star Binaries

We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries.First, procedures for a jerome brown jersey solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-equilibrium sequence and mass-shedding limit, of the high-precision computation, read more are summarized.Then, the current status of numerical-relativity simulations for the merger of BH-NS binaries is described.We summarize our understanding for the merger and/or tidal disruption processes, the criterion for tidal disruption, the properties of the remnant formed after the tidal disruption, gravitational waveform, and gravitational-wave spectrum.
