Outline

This course covers the basic techniques and methods used in modern theoretical astrophysics and deals with a broad range of topics related to stars, galaxies and the universe.

Main topics include:

  1. Course description
  2. Introduction
  3. Properties of stars (Slides, Notes)
    Additional material:
    • Physical constants, Astrophysical constants
    • Blackbody curves & UBV Filters: This is an interactive interface where you can see how the blackbody Planck distribution changes as a function of temperature and the effect of different filters.
    • Hydrogen Energy Levels: Here you can get insight in the energy levels of hydrogen and the population of the different levels with temprature.
    • Eclipsing Binary: Explore the orbits of two eclipsing binaries and how the emitted light changes with the phase of the orbit.
    • Hertzsprung-Russell Diagram: Here you can explore where a star will appear in the Hertzsprung-Russell diagram depending on its luminosity and temperature.
    • Gaia Sky: Open source 3D Universe visualization platform using the Gaia star catalog.
