Press, ISBN 0 521 52927 1 Another book, which you do not have to buy, but may find it useful in the long run if you are majoring in astrophysics, is "An Introduction to Modern Astrophysics", by B. Carroll & D. Ostlie, QB461 .C35 1996. In addition, we may distribute some readings in the class or via the course webpage. Grading: 40% homeworks+lab, 30% midterm, 30% final Late homework penalty: -50% per day or fraction thereof. We will give indulgences only for really good reasons (sickness, if you have a note from the doctor; death in the immediate family; being abducted by a UFO, with a convincing proof; etc.). No late exams will be accepted, except maybe for -very- serious health related reasons. Collaboration policy: NO collaboration is allowed for the final and midterm exams. For the homeworks, you can discuss the problems with other students, but only in general terms, and you have to derive your own solutions. You CANNOT use any old homework solutions from anyone or anywhere. Honor code applies. -------------------------------------------------------------------------------- Lectures (slightly revised): Tue Sep 28 Introduction and overview; cellestial sphere, time systems, units Fri Oct 1 Telescopes, observatories, surveys, astronomical data, web astronomy Tue Oct 5 Astronomical instruments, techniques, fluxes, magnitudes, etc. Fri Oct 8 Celestial mechanics, Kepler's laws, binary stars and their uses Tue Oct 12 Electromagnetic radiation and its interaction with matter Fri Oct 15 Stellar atmospheres, classification of stellar spectra Tue Oct 19 Stellar interiors, energy generation, main sequence Fri Oct 22 The Sun, neutrino astronomy Tue Oct 26 Post-MS evolution, stellar pulsation Fri Oct 29 White dwarfs, neutron stars, black holes Tue Nov 2 Close binaries, stellar interactions, novae Fri Nov 5 Supernovae, GRBs, and their uses Tue Nov 9 Interstellar matter, star formation Fri Nov 12 * Extrasolar planets, life in the universe, SETI, etc. Tue Nov 16 Star clusters and elementary stellar dynamics Fri Nov 19 Our Galaxy: structure, content, rotation, kinematics, stellar populations Tue Nov 23 Stellar luminosity and mass func's, formation and history of our Galaxy Tue Nov 30 Galactic morphology and spiral structure, dark matter, galaxy evolution Fri Dec 3 The final review lecture, or some special topic(s) * Nov 12 lecture will almost surely be rescheduled at some make-up time
