AST 221: Stars & Planets
Fall 2017, Marten van Kerkwijk
Time: MWF12 (MW lectures and F tutorial, typically), starting Sep 11
Place: Cody Hall (AB 107; AB is the Astronomy Building)
Note: the tutorials form an important part, being not just help
sessions, but another form of lecture. During the tutorials, we
discuss specific issues typically not covered (well) by the textbook,
where we can apply what we have learned. The issues discussed are
flexible (I am open to suggestions), and the format is intended to be
as interactive as possible.

next class, i.e., within one or two working days; hence, do not e-mail
about problem sets the day before they are due!]

This is a required course in
all Astronomy & Astrophysics programs. In it, physical
concepts and mathematical tools developed in first-year courses (see
prerequisites) are used to gain an understanding
of stars and planets. Issues covered include the structure of stars
and planets, their formation, stellar evolution, and stellar corpses.

This book is rather expensive. However, it will be used as a
textbook for this course and for AST222 (partly), as well as for
Lecture notes, reading assignments and problem sets will be posted
Problem sets (35%)
Oral Presentation (10%)
Term Test (20%, or 0% if made worse than final)
Final examination (35%, or 55% if made better than term test)
There will be five problem sets due at the start of class on Fridays
as specified in the
Calendar (pdf will be posted there too).
Grades for sets handed in late by will be reduced by one third per
working day. You are encouraged to discuss the problem sets
with each other but should otherwise work individually.
There will be student presentations in the second half of the
term. These will be about 10 minutes long (half presentation, half
discussions/questions) by each group of two students, on an approved
topic (see suggestions). You can start
forming your own team and inform me of your choice of topic starting
from Oct. 11th, but no later than Oct. 23rd. If you decide to drop the
course (the mid-term grades will be posted Nov. 3rd), please inform
your partner in time.
The mid-term will be an in-class, open-book exam of 1 hour duration
and the final exam will be a closed-book exam of 3 hours duration
(only calculator allowed).
A student who is unable to write the term test because of illness,
will be allowed to take a make-up test (likely as an oral exam)
provided s/he notifies me within one week after the
test was written. See Faculty of Arts & Science Calendar, rules
& regulations, for the procedure and required documentation.
