Effects of nuclear matter parameters on the outcomes of binary neutron star mergers

POSTER

Abstract

We present the results of binary neutron star merger simulations in the 3D numerical relativity framework (Whisky-THC) for nine equations of state constructed by varying the nuclear physics parameters. We report various observable outcomes and their possible correlations with the nuclear parameters. We find that the average antineutrino luminosity increases as we increase the value of Ksym which increases the maximum entropy as well as maximum Ye value in the ejecta via neutrino irradiation. We also find that several quantities show a hint of extrema (min/max) behavior at certain values of the nuclear parameters (peak post-merger GW frequency, fpeak vs Lsat). We discuss the possibility of putting constraints on nuclear parameters by observing multiple BNS events in current and planned GW detectors.
