Dynamical tides and gravitational scattering — •Jan Steinhoff — Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Potsdam, Germany

Gravitational wave astronomy offers a promising tool to infer the nuclear physics of neutron stars from observations of inspiraling and merging binaries. This talk addresses the necessity to accurately model dynamical tidal effects during the inspiral, for instance the resonant excitation of neutron star oscillation modes, for the era of third generation detectors. For this purpose, a fully relativistic effective-field-theory model for tidal effects is put forward. Gravitational scattering is discussed as a promising Gedanken experiment to determine the tidal parameters of the model, and for modeling binary systems in general.
