Molecular Clouds Close to the Galactic Center

Abstract

We demonstrate that the accretion disk model for the Galactic Center region by Linden et al (1993a) is applicable for at least one order of magnitude in radius from the Galactic Center (10 ... 100 pc). The viscosity $ν$ is shown to be weakly dependent on the radius $s$: $ν\sim s^{0.4}$. Finally, we discuss the influence of the inner boundary on the structure of the inner disk regions.
