Hydrodynamical activity in thin accretion disks

Abstract

An asymptotic treatment of thin accretion disks, introduced by Klu��niak & Kita (2000) for a steady-state disk flow, is extended to a time-dependent problem. Transient growth of axisymmetric disturbances is analytically shown to occur on the global disk scale. The implications of this result on the theory of hydrodynamical thin accretion disks, as well as future prospects, are discussed.
