Gravitational radiation from binary neutron star mergers: Magnetic and microphysical effects

ORAL

Abstract

Binary neutron star mergers will be important sources of gravitational radiation for Advanced LIGO. Understanding how different physical processes--such as magnetic and microphysical effects due to equations of state or neutrino cooling--are imprinted on the radiation is important for learning more about these systems. We perform a series of binary neutron star mergers to examine some of these effects on the gravitational radiation. We use three different realistic equations of state, ranging from soft to stiff, initially magnetized stars, and include neutrino cooling of the post-merger system using a leakage scheme. We discuss possible observational signatures for these systems.
