The goal of this course is to familiarize you with our current theoretical and observational understanding of stars and stellar processes, and provide a foundation for further studies of galaxies and the Universe. The topics we will cover include: 1. Basic astronomical concepts of position, magnitudes, distance scales, electromagnetic spectrum; 2. Stellar imaging and astrometry (parallax and proper motion, interferometry); 3. Stellar spectroscopy (blackbody radiation, line and band absorption/emission, stellar classification); 4. Stellar atmospheres (radiative transfer, opacities, line profiles); 5. Stellar interiors (hydrostatic and radiative equilibrium, stellar energy sources, elemental synthesis, pulsation); 6. The Sun (helioseismology, solar activity and cycles) 7. Star formation (properties of the interstellar medium and giant molecular clouds, protostellar formation, Jean’s criteria, pre ­main sequence evolution, disks, planet formation); and 8. Stellar evolution (post ­main sequence evolution, white dwarfs, neutron stars, supernovae and gamma ray bursts) Stellar astrophysics touches upon many areas of physics: classical mechanics and gravitation, radiation, thermodynamics, nuclear physics, quantum mechanics, E&M and general relativity. Emphasis will be placed on how these physics topics are used in stellar astrophysics and the observations that frame our current understanding of stars. As such, you should have completed the Physics 2 or 4 sequence to take Physics 160 (exceptions will be considered). You should also be familiar with general computational techniques and tools (e.g., Mathematica, Matlab) and/or programming languages (Fortran, C, Python, IDL), which will be called upon for homework assignments. GRADING Homework constitutes 25% of your grade. There will be 7 homework assignments throughout the quarter; the first is due on September 30th. I will drop your lowest homework grade. Assignments will be posted weekly on the Thursday proceeding the homework topic, and will be due the following Friday by 5pm at my office. Late assignments will be Page 3 of 5 Physics 160 Fall 2011 Course Information not be accepted. Assignments will consist primarily of problems within and outside of the textbook. Some problems will require numerical computation, so please be (or become) familiar with computational programs such as Mathematica, Matlab, IDL or any another programming language. You may work together on homeworks, but the work you hand in must be your own. You may not use prior year’s solutions, online solution or solutions from the book.. Anyone suspected of copying solutions is in violation of UCSD’s integrity policy and will receive a failing grade and be referred to the Office of Academic Integrity. Midterm exam will constitute 20% of your grade each. It will be held in ­class on Thursday, October 27th and cover material up through the 5th week of the course (see syllabus). The exams will consist of short answer and calculation problems, and relevant equations will be provided. More details on the exam will be provided later in the term. There is no final exam. A term project constitutes the remaining 35% of your grade. The term project can be on any topic covered during the course, and will consist of: 1. A project proposal, including outline and references, due at the end of lecture on Thursday, November 10th (5%); 2. A project report (5 ­10 pages, including figures and references), due at the end of lecture on Thursday, December 1st (20%); 3. A 5 ­7 minute presentation made during the “final exam” on Thursday December 8th from 3 ­6pm (10%); Term projects must be done on your own. Plagiarism rules will be strictly enforced. Copying any portion of your paper or presentation from anyone or any source is not allowed, with the exception of short passages that should be explicitly quoted and properly attributed. Details of the term paper will be provided by the 3rd week. Class attendance is not formally required for the lectures, but strongly recommended. Here is a rough breakdown in letter grades (plus and minus grades will be awarded within these ranges): Page 4 of 5 Physics 160 Fall 2011 Course Information Letter Grade A B C D F % Required ≥ 85 70 ­85 55 ­70 40 ­55 < 40 Grade appeals over the grading of the homework or term study are allowed but must be emailed to Prof. Burgasser within one week of receiving that assignment’s grade. Scheduling conflicts due to athletic or artistic performance must be reported at least one week in advance and must be accompanied with a letter from coach/instructor. Homework must be turned in before the conflict; exams must be taken before the conflict. Medical excuses must be accompanied by a physician’s note. OTHER COURSE DETAILS Add/Drop: Use WebReg to add/change/drop, drop from waitlists. If you have any problems using WebReg, see Sharmila Poddar ([email protected]) in 2561 Mayer Hall Annex. Special Needs: The UCSD Office for Students with Disabilities (OSD) is available to work with students with disabilities to facilitate accommodations due to disabilities. These include adaptive software and technologies, captioning and interpreters, AS and peer notetakers and exam modifications. Students requesting these services must obtain and submit an Authorization for Accommodation (AFA) letter to the instructor no earlier than 3 working days prior to receiving accommodations (i.e., exam date). For more information, see the OSD website ( Academic Integrity: Please read “UC Policy on Integrity of Scholarship” in the UCSD General Catalog. Any students caught cheating or plagiarizing will be reported to the Office of Academic Integrity and may be expelled from the course. Page 5 of 5 ...
