WebMergers of neutron stars with black holes have been suggested as candidates for short gamma-ray bursts. They have also been studied for their potential as gravitational wave sources observable with ground-based detectors. For these purposes, it is important to know under what circumstances such a merger could leave an accretion disk or result ... WebThe Schwarzschild radius of a black hole is probably the closest we can get to your question. r s = ( 2 G / c 2) ⋅ m, with 2 G / c 2 = 2.95 km / solar mass. This means, that the Schwarzschild radius for a given mass is proportional to that mass.
