Coalescing binary neutron stars (NS) are expected to be an important source of gravitational waves (GW) detectable by laser interferometers. We present here a simple method for determining the compactness ratio M/R of NS based on the observed deviation of the GW energy spectrum from point-mass behavior at the end of inspiral. Our method is based on the properties of quasiequilibrium binary NS sequences and does not require the computation of the full GW signal h(t). Combined with the…

Neutron star equation of state via gravitational wave observations
Gravitational wave observations can potentially measure properties of neutron star equations of state by measuring departures from the point-particle limit of the gravitational waveform produced in
Searches for Gravitational Waves from Binary Neutron Stars: A Review
A new generation of observatories is looking for gravitational waves. These waves, emitted by highly relativistic systems, will open a new window for observation of the cosmos when they are detected.
Effects of Neutron-Star Dynamic Tides on Gravitational Waveforms within the Effective-One-Body Approach.
A novel effective-one-body waveform model is developed that includes, for the first time, dynamic tides of the neutron star as well as the merger signal for neutron-star-black-hole binaries, and derives an effective description that makes explicit the dependence of matter effects on two key parameters: tidal deformability and fundamental oscillation frequency.
Spectral classification of gravitational-wave emission and equation of state constraints in binary neutron star mergers
The first detection of gravitational waves from a binary neutron star merger (GW170817) and the accompanying electromagnetic emission has impressively advanced our understanding of the merger process
Constraining neutron-star tidal Love numbers with gravitational-wave detectors
Ground-based gravitational wave detectors may be able to constrain the nuclear equation of state using the early, low frequency portion of the signal of detected neutron star--neutron star inspirals.

Prior to the observation of a double neutron star inspiral and merger, its possible implications were striking. Events whose light and gravitational waves are simultaneously detected could resolve
Probing strange stars with advanced gravitational wave detectors
When a neutron star is compressed to huge densities, it may be converted to a strange star. In property of the event/year rate of a neutron star - strange star binary system, we show that the
Properties of double neutron stars
We summarize our studies on properties of double neutron stars observable in gravitational waves and in the radio. Binary population synthesis is used to calculate expected masses of neutron stars in
Status of neutron star–black hole and binary neutron star simulations
We review the current status of black hole–neutron star and neutron star–neutron star binary merger calculations, focusing on recent results about gravitational wave signals and the characteristics
