Hawking temperature of black holes

WebFeb 3, 2024 · The Hawking luminosity \(L\) of the black hole is given by the usual Stefan-Boltzmann blackbody formula \[ L = A \sigma T^4 \] where \(A = 4\pi r_s^2\) is the surface … Webthe black hole starts from the Hawking temperature and nally vanishes when taking into account the quantum backreaction. In the end, the black hole temperature approaches zero, which implies that the radiation temperature should also be zero in the quasi-equilibrium assumption. Now, one might wonder how the black hole temperature could …
