On Thermal Radiation of Black Holes
arXiv:1001.3770
Abstract
We calculate the photonic frequency-dependent absorption cross section and intensity of the Hawking radiation for a stationary non-rotating black hole using the electrodynamic membrane paradigm and Kirchhoff's law. A remarkable conclusion is that the use of geometrical optics limit for absorption cross-section and Kirchhoff's law for the photonic luminosity of black hole provides a very good estimation for its total emission power
