Abstract

In this paper, we explore the prospect for improving the measurement accuracy of masses and radii of neutron stars. We consider imminent and long-term upgrades of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo, as well as next-generation observatories—the Cosmic Explorer and Einstein Telescope. We find that neutron star radius with single events will be constrained to within roughly 500 m with the current generation of detectors and their upgrades. This will improve to 200, 100 and 50 m with a network of observatories that contain one, two or three next-generation observatories, respectively. Combining events in bins of 0.05⁢
