Elliptical accretion disks predict sub-Eddington luminosities and emit mainly at the photon-trapping radius of thousands of Schwarzschild radii with a blackbody spectrum of nearly single temperature of typically about 3X10^4 K. Because of the self-regulation, the photon-trapping radius expands and contracts following the rise and fall of accretion rate.
