Astrophysics III : Stellar and galactic dynamics

PHYS-401

Enseignant(s) :

Kneib Jean-Paul Richard

Langue:

English

Summary

The aim of this course is to acquire some knowledge on specific dynamical phenomena related to the origin, equilibrium, and evolution of star clusters, galaxies, and galaxy clusters.

Content

1. Introduction: distances, sizes, masses of stellar dynamics systems such as star and galaxy clusters.

 

2. Potential theory.

 

3. The orbits of stars.

 

4. Equilibria of collisionless systems.

 

5. Stability of collisionless systems.

 

6. Disk dynamics.

 

7. Kinetic theory: relaxation processes, thermodynamics of self-gravitating systems, Fokker-Planck approximation.

 

8. Collisions and encounters of stellar systems
