Equilibrium configuration for an inertially dragged viscous fluid around a slowly rotating compact object

It is shown that physically meaningful fluid distributions in the form of a thin disk around a rotating compact object can exist in equilibrium where the angular velocity of the fluid is entirely due to the dragging induced by the space-time surrounding the compact object. The pressure balance at the inner edge is mainly due to the equality of the radiation pressure and the hydrostatic gas pressure. If there is no bulk viscosity the pressure remains constant throughout the disk whereas with increasing bulk viscosity the pressure drops in the inner regions but soon stabilizes at an almost constant value.
