Astrophysics - Graduate Studies

 

The list below includes most of the graduate courses for students specializing in Astrophysics. Some of the courses are given every other year. Detailed prior requirements, syllabi and timetables can be found in the list of courses published yearly by the Faculty of Exact Sciences in the Course Catalog (Yedion). Each graduate student's program of studies must be approved by the graduate student advisor.
