 +==== Effect of neutron-star dynamic tides on gravitational waveforms and implications for probing ultra-dense matter ====

 +The recent first detections of gravitational waves with Advanced LIGO have opened a unique channel for probing fundamental physics and astronomy. One of the major scientific prospects with gravitational wave observations is to measure the equation of state of ultra dense nuclear matter in neutron stars. In a binary inspiral, the signatures of neutron star matter in the gravitational wave signal arise from tidal interactions. The dominant effect is due to adiabatic tides and characterized by the neutron stars’ tidal deformability or Love number parameters. Dynamic tides related to the neutron stars’ fundamental oscillation modes also appreciably influence the signal. I will discuss these effects, their inclusion in the Effective-One-Body (EOB) waveform model, and tests against results from numerical relativity simulations. Additional information on neutron star interiors comes from the possible tidal disruption of neutron stars with black hole companions that can occur within LIGO’s most sensitive band and is now also included in the EOB model as I will describe. I will also outline major open issues for future work.
