Abstract

We report our recent results obtained from numerical-relativity simulations of black hole-neutron star binary mergers with a variety of equations of state and black hole spins. The tidal disruption of the neutron star occurs even for high mass-ratio binaries of MBH/MNS = 5, if the black hole has a sufficiently large prograde spin. Information about the equation of state at high density can be obtained from observations of gravitational waves, especially from the cutoff frequency shown in the spectra.
