Stellar & Galactic Dynamics

This lecture series covers topics such as the standard model in cosmology, the Milky Way galaxy, stellar orbits in different potentials, equilibria of collisionless systems, and the stability of rotating disks. The instructor, Dr. Yves Revaz, explores various theoretical and observational aspects of stellar and galactic dynamics, including the distribution functions of stellar systems, the Jeans equations, and the stability of collisionless systems. The course delves into the complexities of galactic structures, such as the Milky Way's bulge, disk, and halo, and discusses key numbers related to the Milky Way's stellar disk, like surface brightness and circular velocity. Additionally, it touches upon gaseous components like the disk and high-velocity clouds.
