**TA:** Elisabeth Krause

**Class times:** Mon,Wed, 10:30-noon in Cahill 211

**Class description:
** Physics and astrophysics of the
interstellar medium

**Prerequisites:**
Basic undergraduate
physics and the physics of radiative processes at the level of Ay121.

**Homework: **There
will be problem sets
assigned the
first class of every week that will be due the first class of the
following
week, at which point solutions will be handed out. ** There
will
be no extensions. **Completion of all the homeworks,
with one
exception,
is required for the class. If
you turn in all
the
problem sets, your lowest score will be dropped when we calculate the
grade. You
will get the most out of
the
class if you make a real effort to solve all the problems by
yourself. If you are truly stuck, you may consult
the
literature, a
classmate, or TA for inspiration. However, once you have
received
whatever minimal hints you need to get going, you should then
go
back and solve the problems and write out the solutions entirely on
your own.

**Grade:
**50% homework
and 50% final exam. NOTE: Completion of ALL of the problem sets, and all on time (!!), is
required.

**Some possibly useful
books (on reserve in the
library):**

The Physics and Chemistry of the Interstellar Medium, A. G. G. M. Tielens (This will be the textbook. The book has a web site, with problem sets, at http://www.cambridge.org/9780521826341)

Physics and Chemistry of the Interstellar Medium, Sun Kwok

Physical Processes in the Interstellar Medium, Lyman Spitzer

Astrophysics of Gaseous Nebulae and Active Galactic Nuclei, Osterbrock and Ferland

The Formation of Stars, Stahler and Palla
