Accretion Disc Viscosity

Part of the Astrophysics and Space Science Library book series (ASSL, volume 208)


We review the various physical processes that could lead to viscosity in accretion discs. A local magnetic dynamo offers the most plausible mechanism and we discuss a simple model in some detail. The dynamo operates even in partially and very weakly ionized discs without much modification.
