  The detection of gravitational waves from a neutron star merger has opened up
the possibility of detecting the presence or creation of deconfined quark
matter using the gravitational wave signal. To investigate this possibility, we
construct a family of neutron star matter equations of state at nonzero density
and temperature by combining state-of-the-art nuclear matter equations of state
with holographic equations of state for strongly interacting quark matter. The
emerging picture consistently points toward a strong first order deconfinement
transition, with a temperature-dependent critical density and latent heat that
we quantitatively examine. Recent neutron star mass measurements are further
used to discriminate between the different equations of state obtained, leaving
a tightly constrained family of preferred equations of state.
