Topics & Readings
Astronomy 2292 is the second semester of a two-semester introductory sequence designed for
Astronomy and Astrophysics majors and minors, as well as for scientifically literate undergraduates
who wish to learn basic astrophysics from a quantitative perspective. The major topics to be covered
- Properties of Stars, including Stellar Atmospheres and Stellar Interiors
- The Interstellar Medium
- Galaxies: Ours and others, active and inactive
- Cosmology and the history of the Universe
The textbook for this course is Foundations of
Astrophysics by Barbara Ryden and Bradley Peterson, available
from the bookstore and many fine online booksellers. This textbook is
required for all students. Selected
readings are assigned weekly, and should be read before the
week's class sessions.

Your final grade will be based on four components. Attendance and class participation (5%),
three problem sets (5% each, for a total of 15%), three interim examinations (20% each,
for a total of 60%), and the final exam (20%).
There will be 3 problem sets for this class. They will be posted
below when the are ready to be distributed, along with the due date. Together they will account
for 15% of your grade. In general, late homework will not be accepted for credit
except for prior approval from the professor.

There are 3 in-class, closed-book, closed-notes examinations at roughly
monthly intervals as follows:
- Exam 1: Friday, February 5, 2016 Exam #1 Study Guide
- Exam 2: Friday, March 4, 2016 Exam #2 Study Guide
- Exam 3: Friday, April 8, 2016 Exam #3 Study Guide
Each exam is worth 20% for a total of 60% of your final course grade.
See the Syllabus for details on the grading and
make-up exam policy. See the In-Class Exam Rules for how we will
conduct the in-class exams.
The Final Examination will be
Tuesday, May 3 from 12:00-1:45pm in 1048 Smith Lab
The final exam will be comprehensive, covering all lectures and
assigned readings. It will be in the same format as the in-class
exams, but longer and cover the entire semester. The final will be
20% of your course grade.
Attendance for the Final Exam is mandatory, and no makeup
final will be offered. If you should miss the final exam, you
will receive a failing grade unless you contact the professor
by 5pm on Friday, December 18 and arrange for a make-up exam
at the start of Spring Semester. In the interim you will automatically receive a grade of
incomplete (I) until the interim exam is graded.
In keeping with University policy, no early "senior" final exams
are given: graduating seniors must take the final exam with the rest
of the class.
I will occasionally be using Carmen to send emails or provide
supplemental files (notes, handouts, Powerpoint slides, etc.).
I will not be using Carmen for grading. If you would like your
current grade at some point during the semester, please contact me or
the TA. Because of the many privacy safeguards mandated by federal
law under FERPA, I can
only respond to email queries regarding your grades or status if you
use your official OSU email@example.com address. This is the only way I
can be sure that the recipient of the email is the person registered
in the class.
Final grades will be posted to the Registrar's system as soon as they are
Readings refer to chapters in Foundations of
Astrophysics. Note that we will not follow the book strictly.
In particular, we may change the order of the topics and skip some
topics entirely. I may also supplement material in the book with
additional notes or handouts. Do not be alarmed.
