Topics listed in square brackets may be included if time permits 1. Preliminaries: Constituents of the universe; observables; scales and units 2. Stars: Classification (HR diagram); structure (hydrostatic equations, [polytrope models]); evolution (nuclear energy production); compact stars (Chandrasekhar limit, white dwarfs, neutron stars, black holes); star formation; [binaries]. 3. The interstellar medium: physical properties of gas and dust; HII regions; neutral hydrogen 4. Stellar systems and stellar dynamics: Classification and morphology (clusters, galaxies, clusters of galaxies); Potentials, orbits and integrals of motion, collisionless systems (Jeans equation; virial theorem, Jeans theorem); kinetic theory (gravothermal catastrophe, relaxation, collisions, dynamic friction); [structure of the Milky Way] 5. Basic concepts in cosmology: isotropy and homogeneity, Hubble expansion; Curved spacetime; Friedmann eq. and cosmological models; cosmological parameters; distance measures; nucleosynthesis; recombination; cosmic microwave background (horizon problem); structure formation via gravitational instability (Jeans instability); evidence for dark matter and dark energy 6. Massive black holes and active galaxies: AGN phenomenology (Quasars, Seyfert galaxies, radio galaxies); quiescent black holes (black hole demographics); accretion (spherical, alpha disk); absorption lines and the inter-galactic medium; [gravitational lensing; stars near black hole]
