Stability of an isothermal disc with three-dimensional magnetic fields and radial viscous force

Ding Shixue  
The stability of an isothermal thin disk with three-dimensional magnetic fields and radial viscosity force is examined in this paper. We find that the radial viscous force has no influence on stability of viscous modes. But there are more influence on the stability of magneto-acoustic modes, which is related to the perturbation wavelenth and different parts of disc .Finally, we use our model to explain the long term variability of Quasar 3C345.
