Inferring the neutron star equation of state from binary inspiral waveforms

Abstract

Gravitational waves emitted from binary neutron stars during their late inspiral and merger contain imprints of the neutron star equation of state. Measuring departures from the point-particle limit of the late inspiral waveform allows one to measure the equation of state properties via gravitational wave observations. This and a companion talk by J. S. Read reports a comparison of numerical waveforms from simulations of inspiraling neutron star binaries, computed for equations of state with varying stiffness. We calculate the signal strength of the difference between waveforms for various commissioned and proposed interferometric gravitational wave detectors and show that observations at frequencies around 1 kHz will be able to measure a compactness parameter and constrain the possible neutron equations of state.
