Schedule, syllabus and examination date

Choose semester

Course content

An introduction to basic aspects of the interpretation of electromagnetic radiation, including classical electromagnetic radiation processes, quantum mechanical transitions in atoms and molecules, radiative transport in stars and diagnostics of physical conditions in stars from observations and observational techniques.

Learning outcome

After completing the course we expect your competence to include the following:

  • Understand various processes that generate electromagnetic radiation in astrophysical objects.
  • Understand various basic processes that are important for the
    transport of radiation through astrophysical media, for example a
    stellar atmosphere.
  • Be able to extract information on the physical conditions in
    astro-physical objects from electromagnetic spectra.
  • Use numerical tools to analyze model atmospheres and basic processes for the generation of radiation
  • Present the results of the numerical analysis in a written report.
