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.
