Description
Tidal Love numbers quantify the deformability of compact objects under external tidal fields. They are key quantities in gravitational‑wave astronomy for accurately modeling waveforms during the final orbits of an inspiral and are tightly connected to the microphysics of the compact object. I will present a framework for computing tidal Love numbers beyond linear order by matching relativistic perturbation theory of compact objects (Schwarzschild black holes and neutron stars) with the worldline effective field theory approach used to define their tidal deformability.
