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)
The material of the two previous lectures is covered on these notes. The notes also introduce the basic equations of radiation transport.
- Energy transport (notes,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 (notes)
Lane-Endem Wolfram Demonstration Project (Slightly Modified version
from the project available
here)
- The Insterstellar Medium and Star Formation (Slides,Notes)
- Stellar evolution and supernova
explosions
S. Woosley and H.-Th. Janka, The physics of core-collapse supernovae
- The degenerate remnants of stars
(Slides,Notes)
Richard R. Silbar and Sanjay Reddy, Neutron
stars for undergraduates,Erratum (article discussing several aspects of the lecture and their extension
to neutron stars)
Mathematica notebook computing the structure of White Dwarfs and
Neutron stars (Notebook, pdf)
- The Milky Way
- The Nature and Evolution of
Galaxies
- Active Galaxies and the Structure of the universe
Excercise Sheet 6
- Cosmological models
(Notes, Slides)
Excercise Sheet 7
- Evolution of the Universe
(Notes, Slides)
The values of the cosmological parameters used in the lecture have been
obtained from this recent paper of the Planck collaboration: Planck 2015
results. XIII. Cosmological parameters. In some cases values listed in
the astrophyscial constants from the
particle data group are used.
- Observational cosmology
(Notes,
Slides)
Charles L. Bennett, Cosmology from
start to finish (Nice article providing a summary of the main
cosmological
topics discussed in the lectures)
Tutorials by Wayne Hu discussing different aspects of Cosmic Microwave
Background Anisotropies
