# Recommended Curriculum for Astronomy & Astrophysics Majors and Minors

Students who began their degree under quarters will not be penalized as the university moves to a semester schedule, either in terms of progress towards their degree or their expected date of graduation. Ohio State's commitment to this policy is stated explicitly in the Semester Conversion Pledge to Students.

The first term on the new semester system was Summer 2012. Students scheduled to graduate after this date are strongly encouraged to prepare well in advance to minimize potential complications. Effective Autumn 2011 the name of the major and minor programs changed from ** Astronomy** to

**. Below is a summary of how the astronomy and astrophysics major has changed and guidelines on how to plan your coursework to insure a smooth transition.**

*Astronomy and Astrophysics*## Transition Policy

No special transition plan is necessary for the major or minor courses in Astronomy and Astrophysics: nearly all of these courses translate directly from 5-hour quarter courses to 3-hour semester courses. The only exception is Astron 295, a 1-hour quarter seminar that students must take twice on the quarter system. This will be replaced with a 1-hour semester seminar, Astron 2895, which students will take only once. As of Autumn 2012, any student who has completed either one quarter of Astron 295 or one semester of Astron 2895 will be deemed to have met the seminar requirement.

Transition policies for the required or prerequisite physics and math courses have been established by the Departments of Physics and Mathematics, respectively. Students can minimize their own transition difficulties by making sure that they do the following:

**First-year students** in 2011-2012 should refer to the **1 year quarters plus 3 years semesters** transition plan. Students should make certain that they have completed Math 153 and Physics 133 by the end of Spring 2012

**Second-year students** in 2011-2012 should refer to the **2 years quarters plus 2 years semesters** transition plan. Students should make certain that they have completed Math 254, 415, 513, and 568 and Physics 263 by the end of Spring 2012

**Third-year ****students** in 2011-2012 should refer to the **3 years quarters plus 1 year semesters** transition plan. Students should make certain that they have completed Physics 632 and 656 by the end of Spring 2012. Double majors with physics should complete Physics 633 and 657.

## Astronomy and Astrophysics Major Curriculum Under Semesters

The Astronomy Department has adopted the following curriculum for the Astronomy and Astrophysics Major under semesters:

**Notes:**

- An acceptable substitute math sequence is Math 1151 - 1172 - 2173 - 2568 - 2415. More advanced students may also substitute Math 1161 - 2162 in place of Math 1151 - 1152 - 1153 or Math 1151 - 1172 - 2173. Math 1151 - 1152 - 2153 - 2174 and Math 1151 - 1172 - 2173 - 2174 also meet the minimum requirements, but are not recommended for students who plan to go to graduate school in astronomy or physics.
- Only one of Astron 5681 and 5682 will be required
- Math 4551 Vector Analysis is also recommended for students who plan to go to graduate school.
- Math 2255 Differential Equations and Their Applications is an acceptable substitute for Math 2415
- Only one of Physics 5401 and 5501 will be required.
