Web30 Apr 2024 · According to references [ 12, 13 ], the Hawking temperature of a two-dimensional black hole can be found by the following topological formula: (1) where ℏ is the Planck constant, is the Boltzmann constant, c is the speed of light, g is the determinant of two-dimensional Euclidean metric, and is the location of j th Killing horizon. WebReal accretion disks are found to have a fairly large range of exponents a, ranging between 0 to 1, rather than clustering around 0.75 (for example, the model for GRO-J1655-40 by … WebThese curves show one common property that the temperature of the extreme black hole vanishes, which can be strictly proved by substituting (8) into (14). This property means that the evaporation of black holes behaves well; that is, it has no divergency due to the appearance of the minimal length [7]. dickfors
