Phys. Rev. Lett. 84, 3519–3522 (2000)Prospects for Gravitational-Wave Observations of Neutron-Star Tidal Disruption in Neutron-Star–Black-Hole BinariesReceived 8 December 1999; published in the issue dated 17 April 2000 For an inspiraling neutron-star–black-hole (NS-BH) binary, we estimate the gravity-wave frequency ftd 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 ftd depends strongly on the NS radius R, and estimate that LIGO-II (ca. 2006–2008) might measure R to 15% precision at 140 Mpc ( ∼1event/yr under current estimates). This suggests that LIGO-II might extract valuable information about the NS equation of state from tidal-disruption waves. © 2000 The American Physical Society URL:
