Abstract
For an inspiraling neutron-star–black-hole (NS-BH) binary, we estimate the gravity-wave frequency at the onset of NS tidal disruption. We model the NS as a tidally distorted, homogeneous, Newtonian ellipsoid on a circular, equatorial geodesic around a Kerr BH. We find that depends strongly on the NS radius , and estimate that LIGO-II (ca. 2006–2008) might measure to precision at 140 Mpc ( under current estimates). This suggests that LIGO-II might extract valuable information about the NS equation of state from tidal-disruption waves.
