Gravitational wave observations of strongly gravitating

compact objects allow us not only to probe black holes and neutron

stars, but also have the potential to uncover new fundamental physics.

To distinguish black holes from their mimickers, sufficiently

accurate predictions for gravitational wave signatures of these

objects are required. Boson stars, a particular representative of the

larger class of ultra compact objects, can be used to understand the

behavior of these systems and their imprints left on the emitted waveform.

I will discuss the inspiral and merger dynamics of binary boson

stars, focusing particularly on the ringdown phase, and comment

on the appearance of gravitational wave echoes in the post-merger

phase of black hole mimickers more broadly.
