Measurement of the tidal deformabilities of GW170817 component neutron stars using chiral-EFT equations of state
Abstract
The first detection of a neutron star merger dubbed GW170817, in August 2017 by the LIGO-Virgo collaboration (LVC) provided the first opportunity to explore the equation of state (EOS) of supranuclear matter using gravitational waves (GW). Previous work combining parameter estimation with chiral-eft on GW170817 and post-merger observations placed new constraints on neutron star radii and tidal deformability. Here, we use those results to explore under what conditions a binary neutron star or a neutron star black hole binary can be distinguished from a binary black hole using only gravitational wave data.
