Magnetic Interaction between Stars and Accretion Disks

Abstract

In this review I consider modern theoretical models of coupled star--disk magnetospheres. I discuss a number of models, both stationary and time-dependent, and examine what physical conditions govern the selection of a preferred model.

Invited review at the International Workshop on Magnetic Fields in Star Formation (Madrid, April 21--25, 2003)
