Schematic representation of binary neutron star merger outcomes. Panels A and B: Two neutron stars merge as the emission of gravitational waves drives them towards one another. C: If the remnant mass is above a certain mass, it immediately forms a black hole. D: Alternatively, it forms a quasistable ‘hypermassive’ neutron star. E: As the hypermassive star spins down and cools it can not support itself against gravitational collapse and collapses into a black hole. F, G: If the remnant’s mass is sufficiently low, it will survive for longer, as a ‘supramassive’ neutron star, supported against collapse through additional …
