Stars: Stellar Atmospheres, Structure, & Evolution

The course is split into two sections: Stellar Atmospheres and
Stellar Structure & Interiors.
The atmospheres part will focus mostly on radiation
transfer techniques: basic definitions, equation of radiation transfer,
moment equations, analytic approximations at small and large optical depth,
the gray atmosphere, Eddington-Milne line formation. At the end
of the atmospheres section I'll be
presenting a few lectures on Monte Carlo radiation transfer techniques
that I use extensively in my own research on circumstellar disks and the
interstellar medium.

Course Texts:

**``Introduction to the Theory of Stellar Structure and Evolution''**
by Dina Prialnick

This is the text for the stellar structure & evolution of the course.

**``Introduction to Monte Carlo Radiation Transfer''**
by Wood, Bjorkman, Whitney & Wolff
POSTSCRIPT
PDF

This is a short booklet that we prepaperd on basic Monte Carlo radiation
transfer techniques. It covers everything I'll present in the Monte Carlo
lectures at the end of the Stellar Atmospheres part of the course. A plane
parallel isotropic scattering code and some three dimensional scattering
codes are available
here.
Other stellar atmospheres books that I'll refer to are:

**``Observation and Analysis of Stellar Photospheres''** by David Gray

**``Stellar Atmospheres''** by Dimitri Mihalas

This book is out of print,
but is in the Physics & Astronomy Library.
It is generally beyond the scope of this short
course, but is the authoratative textbook on the subject.
