Resonances in black hole spacetimes and neutron stars

Joint seminar organized by APC (University of Paris) and Service de Physique Théorique (ULB, Brussels)

Resonances are ubiquotous in nature. In this first part of this talk, I will focus on resonances due to the interaction of two black holes orbiting a central massive black hole. I will discuss both mean motion resonances and tidal resonances in EMRI spacetimes. The second part will be about the resonances in neutron stars. In particular, I will focus on the interface mode that lives near the core-crust boundary and can be excited in the final phases of a binary inspiral. When such a resonance occurs, orbital energy is transferred to the star resulting in the melting of the crust. This is likely observable by the third generation gravitational wave detectors.
