天体物理学项目由天文学系和物理系通过跨部门委员会共同管理。有兴趣的学生必须首先获得这些部门之一的录取权，然后在建立部门居住权后向委员会申请进入该计划。在此程序中，学生可能有资格获得天文学或物理学的硕士学位。天体物理学博士学位论文可由天文学或物理学系的任何合格成员指导。
Students admitted to the Ph.D. program in Astronomy or Physics may petition the Astrophysics Committee for entrance into the Ph.D. program in Astrophysics after establishing departmental residency. Students must complete a minimum of 90 credit hours, including four core graduate courses in Astronomy, four core graduate courses in Physics, plus one additional core course in either Astronomy or Physics. By meeting the course requirements for this degree, a student from the Department of Astronomy will automatically fulfill the requirements for a minor in physics.
