Other suggested courses are Physics P309, P400, P401; Mathematics M312, M344; Computer Science A201-A202 or C211-C212; Geological Sciences G121; History and Philosophy of Science X222, X390, X391; Chemistry C117, C118.

Minor in Astronomy and Astrophysics

A program leading to a minor in astronomy and astrophysics is provided for students who have a serious interest in the field but do not plan to major in the subject. To obtain a minor in astronomy and astrophysics, a student must take the following courses: two 100-level astronomy courses (all combinations are acceptable except A100 and A110, or A105 and A110, A221, A222, and one of A305, A320, A451 or A452. Altogether, these provide at least 17 credit hours. A student must take all necessary prerequisites, including some mathematics and physics classes. Substitution of other astronomy courses may be made with the permission of the department. Replacement of 100-level astronomy courses by 300- or 400-level astronomy courses is encouraged. The cumulative GPA of all courses taken for the minor must be at least 2.0.

Departmental Honors Program

The honors program is designed for superior students who plan to pursue graduate studies in astronomy and astrophysics. Students wishing to pursue the honors program should contact the undergraduate advisor in the Department of Astronomy during the second semester of their sophomore year or first semester of their junior year. To be admitted to the honors program, students must have a minimum overall GPA of 3.3 and a minimum GPA of 3.3 in their astronomy, mathematics, and physics courses. Students must maintain these GPAs to receive a degree with honors in astronomy and astrophysics.

In the honors program, students complete the same requirements as the regular B.S. in astronomy and astrophysics and in addition take Astronomy S499 Honors Research. Astronomy S499 is to be taken one or both semesters during the senior year, and counts for 3 credits each time it is taken. Students will carry out research supervised by a faculty member in the department. During the second semester of the senior year, the student will write a research report and make an oral presentation describing the work to the Department of Astronomy in a mini-colloquium.

Recommended Schedule for Honors Astronomy and Astrophysics Program

Freshman
Mathematics M211-M212
Physics P221-P222
Astronomy A221-A222 (Students with good high school preparation in physics and mathematics are encouraged to take A201-A202 during the freshman year.)

Sophomore
Mathematics M311 and M343
Physics P301
Astronomy A221-A222 (if not taken during freshman year)

Junior
Physics P331-P332 and P453 (if taking the P453-P454 sequence). (P453 is taught in the spring semester, and P454 is taught in the fall semester.)
Astronomy A305, A451, A452, or A453 (A305, A452, and A451 are offered in alternative years).

Senior
Physics P441-P442 or P454
Astronomy A305 and S499. A451, A452, or A453

Note: A100, A102, A105, A110, and A115 are introductory astronomy courses of comparable difficulty. No one of them is considered a prerequisite for any other. A110 is a survey of all modern astronomy in one course. A100 and A105 divide the A110 material into two parts. Taken together, A100 and A105 cover essentially the same material as A110 but in greater depth. A102 covers selected topics in astronomy with an emphasis on the role of gravity. A115 is an introduction to cosmology that also covers many topics in basic astronomy.
