The Shakura-Sunyaev viscosity prescription with variable [alpha] (r)

Almost all hydrodynamic accretion disc models parametrize viscosity with the dimensionless parameter ... There is no detailed model for ..., so it is usually taken to be a constant. However, global simulations of magnetohydrodynamic discs find that ... varies with distance from the central object. A...
