X-ray Astronomy: Early history of X-ray Astronomy in short. X-ray observatories: major past, present and future missions.

Accretion as a Source of Energy: Preliminaries: accretion as powerful astrophysical energy source, accretion efficiency, characteristic temperatures, Eddington limit. Wind and Roche-lobe fed binary systems.
Local structure of thin disks (standard SS model). Disks with advection and complete topology of solutions. Optically thick, cold disks: free-free emission-absorption. Optically thin, hot corona: thermal comptonization.

High Energy Emission in Binary Systems: Black Hole binaries. Spectral features: iron lines and reflection components. Dwarf Nova outbursts: the Galactic BHC GRS 1915+105. Neutron Star binary systems: Low and
High Mass X-ray Binaries. X-ray pulsars Rapid variability in binary systems: power spectrum and Quasi Periodic Oscillations (QPOs).

The Most Powerful Cosmic Explosions: Core collapse and hydrodynamics of the supernova explosion. Physics of the expanding, shocked envelope.

High Energy Emission in Supernova Explosions: Basic SN classification scheme. Early UV flash in core collapse supernova explosions. Circumstellar interaction.
