Spin effects on neutron star fundamental-mode dynamical tides: Phenomenology and comparison to numerical simulations

Gravitational waves from neutron star binary inspirals contain information on strongly-interacting matter in unexplored, extreme regimes. Extracting this requires robust theoretical models of the signatures gravitational-wave signals due to spin and tidal effects. In fact, spins can have a significant impact excitation quasi-normal modes star, which is not included current state-of-the-art waveform models. We develop simple approximate description that accounts for Coriolis effect star's quadrupolar octupolar fundamental incorporate it SEOBNRv4T model. show introduces only one new interaction term an effective action co-rotating frame fix coefficient by considering spin-induced shift resonance frequencies has been computed numerically mode rotating stars literature. investigate relativistic corrections gravitational redshift frame-dragging effects, identify important directions where more detailed developments are needed future.
