Thermal Effects in Binary Neutron Star Mergers

Blog Article

We study the impact of finite-temperature effects in numerical-relativity simulations of binary neutron star mergers with microphysical equations of state and neutrino transport in which we vary FLORABEAR the effective nucleon masses in a controlled way.We find that, as the specific heat is increased, the merger remnants become colder and more compact due to the reduced thermal pressure support.Using a full Bayesian analysis, we demonstrate that this effect will be measurable in the postmerger gravitational wave signal with Blindfolds next-generation observatories at signal-to-noise ratios of 15.
