Advection-dominated Accretion in the Galactic Center and the Appearance of Sgr A*
T. Beckert, W. J. Duschl
Abstract
We present a modified description of advection-dominated accretion flows (ADAF) with a geometrical viscosity. A simplified treatment of the dynamics of the flow in the inner relativistic part is suggested and results are compared with the galactic center source Sgr A*.
