  • The recent discovery by LIGO/Virgo of a merging binary having a ∼ 23M black hole and a ∼ 2.6M compact companion has triggered a debate regarding the nature of the secondary, which falls into the so-called mass gap. Here we explore some consequences of the assumption that the secondary was a neutron star (NS). We show with concrete examples of heretofore viable equations of state (EOSs) that rapid uniform rotation is certainly adequate to explain the existence of a stable ∼ 2.6M NS for… CONTINUE READING
