# ASTR 601, Radiative Processes

# Fall 2023

The production and propagation of radiation, and its application
in a variety of astrophysical contexts. The class textbook is
Rybicki and Lightman, Radiative Processes in Astrophysics, and
the secondary text is Shu, The Physics of Astrophysics: Volume 1,
Radiation. I also recommend that you check out the
online notes by Joern Wilms

## Hints about doing research in
astrophysics

## The Ten Commandments of presentations

## Additional hints about giving talks

## What I hope you learn in the class

These are mainly from stellar astrophysics, but they can
serve as generally useful guides as well.
