FINAL EXAM:  The final exam is a three-hour closed-book exam.  When you have are ready to take the test, and have three continuous uninterrupted hours, then go ahead and print out the test, take it immediately to a quiet and remote area, and complete the exam.  Please turn it in to Marc, his mailbox (outside 151 Bridge annex), or to Shirley Hampton in Bridge annex 151.  Please turn in the test before 5pm on Friday, Dec 9.  Do not look at the test until you are ready to take it.  When you are ready, the test is available HERE.


Class description:   Stellar structure and evolution.  The basic physics, stellar models, evolution from the Hayashi track to compact remnants.  Stellar pulsations and oscillations,  stellar rotation, interacting binaries, and theories of the first (Pop III) stars. 

Prerequisites:  Basic undergraduate physics.  You have also hopefully had
     some undergraduate level class on stars or astronomy more generally.  If
     not, Physics of Stars, by A. C. Phillips, provides a very clear undergraduate
     level introduction that you may want to read.

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 (with only one exception) of the problem sets is required.

Some possibly useful books (on reserve in the library):
          Stellar Structure and Evolution, Kippenhan and Weigert.  This is, I believe, really
          the best book on stellar evolution that I have seen.  It is quite dense and theoretical,
          but it is crystal clear and everything is there.
           Physics of Stars, A. C. Phillips.  This is also an excellent book, with emphasis
            on the physics, but it is at an undergraduate level.  You should know everything
             in this book inside-out.  This class will go into things in more depth than this book.
              Still, most of the final-exam questions will probably be taken from this book.
            Stellar Interiors: Physical Principles, Structure, and Evolution, C. J. Hansen,
            S. D. Kawaler and the newer version with Trimble.  This is a graduate-level text. 
             It is very good in some areas, but others aren't quite as clear.
            Principles of Stellar Evolution and Nucleosynthesis, D. D. Clayton.  This is
            an excellent graduate-level textbook with particular emphasis on nucleosynthesis.
            Galactic Astronomy, Binney and Merrifield.  Although the book is nominally
             on galactic astronomy, it has excellent chapters on stellar evolution and population,
             with particular emphasis on the observational/empirical point of view.
            Black holes, white dwarfs, and neutron stars, Shapiro and Teukolsky.  This is a
            great book on the endpoints of stellar evolution.
            Radiative Processes in Astrophysics, Rybicki and Lightman.  This is an
            excellent textbook for the radiative processes class that you are probably taking
            concurrently with this class.  This book should be useful in this class as well.

           There are tons more books, including the older classics by Chandrasekhar, Cox and
            Giulli, and Schwarzchild, and newer books by Prialnick, Collins, Bohm-Vitense,
            Bisnovati-Kogan, and Padmanabhan and others, that you might find useful.
