Web31 Dec 2014 · 1 Answer Sorted by: 7 It depends on the distance from the central body. This gives the temperature T at a given point as a function of the distance from that point to the center ( R ): T ( R) = [ 3 G M M ˙ 8 π σ R 3 ( 1 − R inner R)] 1 4 Web31 Mar 2024 · The black hole, named 3XMM J215022.4−055108, is indicated by the white circle. The elusive type of black hole was first identified in a burst of telltale X-rays emitted by hot gas from a star as it was captured and destroyed by the black hole. Hubble was needed to pinpoint the black hole's location in visible light.

The four laws of black hole mechanics are physical properties that black holes are believed to satisfy. The laws, analogous to the laws of thermodynamics, were discovered by Jacob Bekenstein, Brandon Carter, and James Bardeen. Further considerations were made by Stephen Hawking. The laws of black hole mechanics are expressed in geometrized units. The horizon has constant surface gravity for a stationary black hole.
