If black holes represent one of
the most fascinating implications of Einstein's theory of
gravity,
neutron stars in binary system are arguably its richest laboratory,
where gravity
blends with astrophysics and particle physics. I will discuss the rapid recent progress
made in modelling these systems and show how the
inspiral and merger of a binary
system of neutron stars is more than a strong source of gravitational waves. Indeed,
while the gravitational signal can provide
tight constraints on the equation of state for
matter at nuclear densities, the formation of a black-hole--torus system can explain
much of the phenomenology
of short gamma-ray bursts, while the ejection of matter
during the merger can shed light on the chemical enrichment of the universe. Finally, I
will review
how our understanding on the maximum mass and radii of neutron stars
has improved with the detection of GW170817.
