Course Goal / Objective
To study mass accretion as an energy source in binary star systems containing compact (tight) objects as well as in active galactic nuclei, and using basic physics knowledge to describe the physical processes involved in accretion disks and other accretion fluxes.
Course Content
Mass transfer mechanism in binary systems, Viscous torques, magnitude of viscosity, Accretion in close binary systems, Stable thin disk, structure of stable Alpha-disk (standard model), Irrediated disks, Accretion on tight bodies (white, dwarf neutron star and black hole)
Course Precondition
none
