Description
The kinetic theory of a self-gravitating system is considered in the framework of Bhatnager-Gross-Krook model. This approach offers a unique and tractable setup for studying the central, collision-dominated region of the system, as well as its outer almost collisionless part. Stationary non-equilibrium states of the system are considered and several different self-similar solutions are identified.
