Effects of a new Equation of State on Binary Neutron Star Mergers

ORAL

Abstract

We present results of fully general relativistic simulations of binary neutron star mergers employing a new cold chiral effective field theory equation of state that we named $BL$. We offer a comparison with respect to a standard relativistic mean field equation of state ($GM3$) and give a full analysis of the dynamics during both the inspiral and post-merger phases. We extract the gravitational wave signal for all our simulations and analyze differences in the signals from different models. We also describe the effects of this new equation of state on the dynamics of the ejecta and on possible electromagnetic counterparts.
