Section Title:
Decadal Survey
Section Info:
Astro 2010: the astronomy and astrophysics decadal survey. Course will be lead by Brian Fields and Charles Gammie. Class will read selected white papers and conclusions for the astronomy and astrophysics decadal survey, discuss what the report reveals about where the greatest opportunities are in astronomical research over the next decade, and discuss implications of priorities set by the report. Students will practice oral presentation skills by giving brief talks introducing a paper. Homework will consist of brief written summaries and reactions to some of the paper. Also offered as 496DS.

Section Title:
Star Formation
Section Info:
Star Formation: ASTR 596 SF This is a seminar course, with approximately half of the semester meetings being lectures and the other half presentations and discussions by students. There are no exams. There will be a paper by each student, which will also be presented orally to the class, on any one of a large number of topics (including observational ones) related to star formation, to be chosen by each student and the instructor. This could be a review of the literature or a short original project. The lectures will focus on the underlying physics of our best understanding of the theory of star formation. This includes (but is not limited to): (i) MHD waves and instabilities including the effects of radiation, thermal conduction and viscosity, and application to phase transitions (e.g., cloud-intercloud) in the interstellar medium; (ii) the angular momentum problem and magnetic braking (detailed analytical and numerical solutions); (iii) the role of ambipolar diffusion in protostar formation and the resolution of the magnetic flux problem; (iv) elements of theory of turbulence and its application to molecular clouds. All physical processes will be synthesized into a testable theory of protostar formation. Close contact with relevant observations will be maintained throughout all topics, both in the form of input to theory as well as in the form of testable predictions by theory. Prerequisites: desire to learn and an open mind! Ast502 is helpful but not necessary (the necessary background will be reviewed at the beginning of the course).
