Black hole luminosity
WebSep 4, 2024 · This question is based on this description of the Cormoran Supermassive Black Hole in the Orion Arm's website:. Surrounding this event horizon is an (apparently artificial) accretion disk about 4AU in diameter, which shines due to internal fusion, with a surface temperature of 5700K and a luminosity of 4500 x Sol. Webin which case the black hole cannot accrete. This is called the Eddington luminosity. A black hole that is twice as massive exerts twice as much gravitational force, so its luminosity …
