Accretion disc viscosity: how big is alpha?

KING A.R., PRINGLE J.E. and LIVIO M.

Abstract (from CDS):

We consider observational and theoretical estimates of the accretion disc viscosity parameter α. We find that in thin, fully ionized discs, the best observational evidence suggests a typical range α ∼ 0.1-0.4, whereas the relevant numerical simulations tend to derive estimates for α which are an order of magnitude smaller. We discuss possible reasons for this apparent discrepancy.
