| Research Abstract |
Binary systems composed of a black hole and a neutron star cannot be in stationary state due to the emission of gravitational waves. There, however, exists a state which can be regarded as quasi-equilibrium, because the time-scale of the orbital decay is much longer than the orbital period. In this research program, we have developed a numerical code to construct relativistic black hole-neutron star binaries in quasi-equilibrium. In particular, we have found a method to include a rapidly spinning black hole in a black hole-neutron star binary.
