Tidal Deformabilities and Radii of Neutron Stars from the Observation of GW170817

ORAL

Abstract

On August 17, 2017 LIGO and Virgo made the first observation of a binary neutron star coalescence, GW170817. We present measurements of the tidal deformabilities and radii of the neutron stars in the GW170817 binary from the analysis of the gravitational-wave data incorporating information from nuclear matter studies. We also briefly discuss prospects for further improvements in the accuracy of parameter measurements and extraction of nuclear equation of state physics from the gravitational-wave data.
