Scientific paper

A rigorous, general relativistic, viscous, fluid-dynamical equation is used to calculate the temperature profile of the accretion disk around a Kerr black hole. The results show that there is a maximum in the profile. If the disk matter radiates like a black body, then the result is independent of the viscosity mechanism and coincides with those based on the classical treatment. For free-free radiation, the temperature profile is also basically the same as in the classical case. The calculation shows that within the radius of the temperature maximum, there exists a rapidly cooling ring-shaped region possessing characteristics that are not found in the case with usual temperature profile.
