Description

This work presents a study of methods useful for modeling and understanding dynamical systems in the Galaxy. A natural coordinate system for the study of dynamical systems is the angle-action coordinate system. New�methods for�the�approximation�of the action-angle variables�in�general potentials are presented and discussed. These new tools are applied to the construction of dynamical models for two of the Galaxy�s components: tidal streams and the Galactic disc. Tidal streams are remnants of tidally stripped satellites in the Milky Way�that�experience�the effects�of�the large scale structure�of the Galactic gravitational potential, while the Galactic disc provides insights into the nature of the Galaxy near the Sun. Appropriate action-based models are presented and discussed for these components, and extended to include further information such as the metallicity of stars.Typham this is the title: Dynamics of the Milky Way Tidal Streams and Extended Distribution Functions for the Galactic Disc
