• Two binary neutron star mergers, GW170817 and GW190425, have been detected by Advanced LIGO and Virgo. These signals were detected by matched-filter searches that assume the star's orbit has circularized by the time their gravitational-wave emission is observable. This suggests that their eccentricity is low, but a direct measurement of their eccentricity has not yet been made. We use gravitational-wave observations to measure the eccentricity of GW170817 and GW190425. We find that the… CONTINUE READING
