This program is appropriate for students interested in a more flexible and diverse undergraduate program. It may be tailored to be a natural counterpart to a second major in Mathematics, Physics or Computer Science; students should consult the undergraduate chairs of Astronomy & Astrophysics and the respective departments for advice on course selection.

(8.0 credits, including at least 2.0 credits at the 300+ level, and a 0.5 credit at the 400-level)

Notes:
1. The Astronomy & Astrophysics Major program is not designed primarily for students intending to pursue graduate studies in Astronomy & Astrophysics. Such students should consider the Astronomy & Physics Specialist program, or consult the Undergraduate Chair about their course selections.
2. Students interested in pursuing a research project in fourth year ( AST425Y1) should consult the undergraduate chair.
3. Third-year students are invited and fourth-year students are expected to attend the weekly departmental colloquia.
