Query: Gravitational Waves from Dark Boson Star binary mergers   Gravitational wave astronomy might allow us to detect the coalescence of
low-brightness astrophysical compact objects which are extremely difficult to
be observed with current electromagnetic telescopes. Besides classical sources
like black holes and neutron stars, other candidates include Exotic Compact
Objects (ECOs), which could exist in theory but have never yet been observed in
Nature. Among different possibilities, here we consider Dark Stars,
astrophysical compact objects made of dark matter such that only interact with
other stars through gravity. We study numerically the dynamics and the
gravitational waves produced during the binary coalescence of Dark Stars
composed by bosonic fields. These results are compared both with Post-Newtonian
approximations and with previous simulations of binary boson stars, which
interact both through gravity and matter. Our analysis indicates that Dark
Boson Stars belong to a new kind of compact objects, representing stars made
with different species, whose merger produces a gravitational signature clearly
distinguishable from other astrophysical objects like black holes, neutron
stars and even boson stars.
