## Abstract We calculate the amount of angular momentum that thermal photons carry out of a viscous black hole accretion disk, due to the strong Doppler shift imparted to them by the high orbital velocity of the radiating disk material. While thermal emission can not drive accretion on its own, we

In thin accretion disks the electromagnetic modes that can transport angular momentum (in the outward direction as needed for accretion to occur) are shown to require, for their excitation, the combined effects of the finite plasma temperature and of the gradient of the rotation frequency (R) in the
The effects of the acquisition of angular momentum on the expansion of homogeneous, ellipsoidal density perturbations is investigated by generalizing the theory of previous papers of this series, where spin grows to the first order in overdensity. A small difference is found to be between the two ca
