The LIGO/Virgo detection
of gravitational waves originating from a neutron-star (NS) merger,
GW170817, has recently provided new stringent limits on the tidal
deformabilities of the stars involved in the collision. In this talk, I
will discuss recent analysis of the implications of this measurement for
the NS-matter equation of state (EoS). In this analysis, we generate
the most generic family of NS-matter EoSs that interpolate between
state-of-the-art theoretical results at low and high baryon density.
This, coupled with with the existence of two-solar-mass stars and the
current LIGO/Virgo constraint allows us to place strict, robust bounds
on, e.g., the maximal masses and radii for a typical 1.4-solar-mass
star. Time permitting, I will also discuss work in progress to improve
upon the perturbative QCD EoS used in this matching, with the aim of
further improving the understanding of the NS-matter EoS.​
