1. Transfer of Angular Momentum in Astrophysical Discs
Sammanfattning : In this thesis a study of astrophysical discs, with emphasis on galactic discs, is presented. The frictional force acting on a small satellite galaxy, moving on a co-planar circular orbit in a galactic disc, is shown to be only weakly dependent on the velocity dispersion and the self-gravity of the disc.
