As an entering graduate student you will be assigned a major professor and a senior graduate student as advisor and mentor. You can change your major professor at will, after consulting with the faculty. You are encouraged to work with a variety of the faculty and research staff during your first two years.
By the time you take the preliminary examination, normally after two years of graduate study, you should have discussed a thesis topic with a professor who will serve as your thesis advisor.
Graduate students from other departments who wish to minor in Astronomy should ask the department for assignment of a minor professor. The minimum requirement for a minor is 10 credits from courses at or above the 500-level, including Astronomy 700 (cross listed courses with other departments are not eligible), and a GPA of 3.0 in the minor courses.
The Astronomy Department does not have a foreign language requirement.
