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:
- Course description
- Introduction
- 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.
- Stellar Structure
- Equation of state (slides)
- Energy transport (slides)
Roger Balian and Jean-Paul Blaizot, Stars
and statistical physics: A teaching experience (article discussing
many of the aspects introduced in the previous lectures)
- Simple stellar models
