Homework
-
HW 1: Properties of light
Due Tuesday, Sep 1, at start of class.
-
HW 2: Stars in the solar neighborhood
Due Thursday, Sep 10, at start of class.
-
HW 3: Stars and radiation
Due Thursday, Sep 24, at start of class.
-
HW 4: Stellar interiors and models
Due Tuesday, Oct 27, at start of class.
-
HW 5: Stellar evolution
Due Tuesday, Nov 10, at start of class.
-
HW 6: Review and comment on student presentations
Due Thursday, Nov 19, and Tuesday, Nov 24, at least 3 hours
before class meets.
Before a presentation is given in class,
read the copy which sits in the "Discussions" section
of myCourses. If you leave a comment in the topic,
providing praise and/or constructive criticism for the
speaker, you will earn credit toward HW 6.
You must comment cogently on at least four presentations
in order to earn full credit. Commenting on additional
presentations can earn extra credit.
Extra credit projects
Extra credit assignments are completely optional.
If you choose to do one,
you can add up to five percent to your overall course score.
Each assignment must be submitted via
the appropriate section of the
Assignments
tab of myCourses.
- I taught a course on stellar astrophysics, but with quite a
different focus, a long time ago. Perhaps some of the
material there could be useful.
- There are some excellent textbooks which are free to read on line;
look in the
ADS Digital Library . For this course, you might consider
- Another set of resources which are free to read online are
the lecture notes written by J. B. Tatum,
of the University of Victoria. For this course, you might examine
- A good history and explanation of spectral classification is
-
Spectral classification
by Apellaniz, Negueruela, and Caballero,
to appear as a chapter in
Encyclopeia of Astrophysics, ed. Mandel & Schneider.
