The dynamics in mergers of binary neutron star (BNS) systems depend sensitively on the equation of state (EOS) of dense matter. This has profound implications on the emission of GW and the ejection of matter in the merger and post-merger phases and is thus of high interest for multi-messenger astronomy.
We perform simulations of equal-mass BNS mergers with a set of 9 different EOS based on Skyrme density functionals systematically varying the effective nucleon mass, incompressibility, and symmetry energy at saturation density. This allows us to investigate the influence of specific nuclear matter properties on the dynamics of BNS mergers. We analyze the impact of these properties on the merger dynamics, the fate of the remnant, disk formation, ejection of matter, and
gravitational wave emission.
