Mass chart for black holes and neutron stars. Masses of stellar remnants are measured in many different ways. This graph shows the masses for: black holes detected by electromagnetic observations (purple); black holes measured by gravitational-wave observations (blue, LIGO-Virgo detectors); neutron stars measured with electromagnetic observations (yellow); and neutron stars detected through gravitational waves (orange, LIGO-Virgo detectors). Highlighted is the GW190521 signal that showed the merger of two black holes with masses 85 and 66 times that of our sun (solar masses), resulting in a black hole with a mass of 142 solar masses. This was the largest merger observed when this chart was published in November 2020. LIGO (Laser Interferometer Gravitational-Wave Observatory) consists of two sites in the USA. The Virgo interferometer is located in Italy. | |
