L = A σ T 4 = ℏ c 6 15360 π G 2 1 M 2. Peak photons are calculated using Planck's radiation law:
WebThe value of Tmax ∼ 1032 K −1/2 is exorbitantly large to be of any use, or so it seemed at least for a long time. Ten years after Sakharov’s result, Hawking derived semi-classically the temperature-mass (M) relation for the evaporation of black holes, T = 1/(8πGN M) = m2Pl /(8πM), with the spectrum of black body radiation [2, 3].
