SUMMARY:Probing the Dense-Matter Equation of State with Neutron Star M
 ergers\, Network in Neutrinos\, Nuclear Astrophysics\, and Symmetries 
 (N3AS) Seminar\, Carolyn Raithel\, Institute for Advanced Study
DESCRIPTION:Binary neutron star mergers provide a unique laboratory fo
 r studying the dense-matter equation of state (EOS) across a wide rang
 e of parameter space\, from the cold EOS during the inspiral to the fi
 nite-temperature EOS following the merger. In this talk\, I will discu
 ss the impact of the EOS on the post-merger phase of a binary neutron 
 star coalescence\, during which time the matter is heated to significa
 nt temperatures and can deviate away from its initial equilibrium comp
 osition. I will present a new set of neutron star merger simulations\,
  which use a parametrized framework for calculating the EOS at arbitra
 ry temperatures and compositions. I will show how systematically varyi
 ng the properties of the particle effective mass affects the thermal p
 rofile of the post-merger remnant and how this\, in turn\, influences 
 the post-merger evolution. Finally\, I will discuss the impact of vary
 ing the slope L of the nuclear symmetry energy on the properties of th
 e post-merger phase. In particular\, I will show that the post-merger 
 gravitational wave emission is mostly insensitive to L\, but that\, in
  contrast\, the dynamical ejecta carry a weak signature of the slope o
 f the symmetry energy.
