Description
Boson stars are compact objects composed of fundamental fields
arising in theories beyond the standard model (SM) of particle physics.
From dark-matter halos to ultracompact objects with light rings,
they have acquired an important role in gravitational-wave driven
searches for physics beyond the "GR+SM" paradigm. In this talk
we present an overview of the modeling of boson-star binaries
as sources of gravitational waves, how present detectors would
interpret their signals and what smoking-gun effects may enable
us to distinguish them from other sources.
