Description

If a star gets too close from a black hole (BH), the former can be disrupted by the tidal forces of the latter, resulting in a luminous event known as a tidal disruption event (TDE). Furthermore, the extreme nature of the system also results in the emission of gravitational waves, which carry additional informations about the properties of the BH and the star. As such, TDEs potentially allow observations of BHs and stars both in the electromagnetic and gravitational spectrum. However, not all TDEs may be detectable, and in order to better prepare future gravitational and electromagnetic missions, we need to understand what will be the properties of these observable events as well as their rates. I will first introduce the framework to address these questions and will present the results for the particular case of LISA.
