Luminosity Limit of Super-Eddington Accretion onto Black Holes

  • The luminosity limit is derived for the Super-Eddington accretion by obtaining the self-similar solution. The maximum luminosity is about 4.0 x 1037 erg/s(M/Mסּ) or so (significantly less than the Eddington luminosity) due to photon trapping although the accretion rate is Super-Eddington. The radiation spectrum is found to be universal as Fν ∝ ν-1.
