Digitale Lehre:
The lecture and exercise classes will be offered in digital form. The lecture material will be presented in a series of videos that are provided on a weekly basis. Once every week (in the lecture/exercise slot on Wednesday) there will be an interactive session, which includes a discussion of the material covered in the lecture, short presentations by the participants on selected topics, interactive computational sessions, or live observations using the TURM Observatory.

- Astrophysical Observables: Distance, Temperatures, Spectra, Luminosity, Radius, Mass
- Electromagnetic Radiation and Matter: Black-Body Radiation, Formation of Spectral Lines, Boltzmann and Saha Equations, Hertzsprung-Russell Diagram
- Stellar Atmospheres: Radiation Field, Stellar Opacity, Transfer Equation
- The Sun: Solar Interior, Solar Atmosphere, Solar Cycle
- Stellar Interiors: Hydrostatic Equilibrium, Equation of State, Stellar Energy Sources, Energy Transport, Stellar Model Building
- Stellar Evolution: Main Sequence and Evolution, Late Stages of Stellar Evolution, Evolution of Massive Stars, Supernovae
- Stellar Remnants: White Dwarfs, Degenerate Matter, Neutron Stars, Pulsars, Black Holes
- Interstellar Medium and Star Formation: Components of the Interstellar Medium, Cloud Collapse and Star Formation
- Galaxies: The Milky Way Galaxy, Nature of Galaxies, Galactic Evolution
- Universe at Larger Scales: Olbers' Paradox, Extragalactic Distance Scales, Hubble's Law
- Big-Bang Cosmology: Newtonian Cosmology, Microwave Background, Early Universe
