REQUIRED TEXTBOOK: Observation and Analysis of Stellar Photospheres
by Gray
This will not be followed religiously. Alternative books are
listed in the first section of the notes that I had hoped to
distribute prior to each class.
Exams and Grading: I expect as graduate students that grades not
to be the obsession that they are with too many undergraduates
at this place. Your primary goal should be to extend your knowledge
into new areas, especially into topics of interest to YOU. This
necessarily means developing greater depth in some fields than
in others. This kind of development is antithetical to the normal
concept of grades.
But (!) this is a core course providing
coverage of material that will be of use to you almost independent
of your field of research interests. And my experience tells
me that what is required to pursue a Ph.D. successfully is not
always understood by the young eager research student. It was
certainly so in my case!
Therefore, I will keep grades. These will
be based on problem sets and a comprehensive final examination.
I may choose to assign a topic to be discussed either in written
form as a short paper or in oral form as a short presentation
in class.
General Remarks: I realize
that our backgrounds are diverse. If you have not previously
covered some of the auxiliary topics-statistical physics, atomic
and molecular spectroscopy, basic astronomy, and the like-speak
up. I can either cover the material or direct you to books and
articles, many of which I have personally found useful. In any
case, I would urge you to READ widely. Astronomy is such a beautiful
subject that what seems to you a digression today may well be
essential tomorrow.
COURSE OUTLINE:
The major topics to be covered are:
Why? What?
Fundamentals of radiative transfer
Thermodynamic equilibrium, local thermodynamic
equilibrium, and the principle of detailed balance
Photon-particle interactions: processes
and concepts
Classical model atmospheres
Line formation, analysis, and applications
Non-local thermodynamic equilibrium
Beyond classical model atmospheres
Special topics (time permitting) including
extended atmospheres
