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.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Space sciencesMathematical physicsStatistical physicsDynamical systemsSpace Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics)https://scigraph.springernature.com/ontologies/product-market-codes/P22030Theoretical, Mathematical and Computational Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19005Complex Systemshttps://scigraph.springernature.com/ontologies/product-market-codes/P33000Statistical Physics and Dynamical Systemshttps://scigraph.springernature.com/ontologies/product-market-codes/P19090Space sciences.Mathematical physics.Statistical physics.Dynamical systems.Space Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics).Theoretical, Mathematical and Computational Physics.Complex Systems.Statistical Physics and Dynamical Systems.523.113Sanders Jasonauthttp://id.loc.gov/vocabulary/relators/aut323318MiAaPQMiAaPQMiAaPQBOOK9910300408103321Dynamics of the Milky Way1771540UNINA
