## Astronomy Major Overview

The** **Astronomy Major at Cornell University is designed to be flexible so that it can be customized to the needs of each student. There is a common core set of courses followed by two concentration paths:

**1) Astrophysics Concentration** is designed for those who intend to go on to graduate school in the physical sciences such as Astronomy, Physics, or Engineering.

**2) General Astronomy Concentration** is intended for students who do not plan on research careers in astronomy, but may have more broad intellectual interests, and are interested in related career paths, such as education or public outreach. The flexibility offered by the General Astronomy Concentration make it suitable to be elected as second major by a broad group of students.

**TO APPLY** for an Astronomy Major make an appointment to visit Professor Phil Nicholson, Director of Undergraduate Studies (astrodus@cornell.edu; office hours - Tuesdays 3:30pm-5:00pm, 418 Space Sciences Building).

## Astronomy Major Core Requirements

(7 courses, 27-28 credit hours total)

- 3 Semester Introductory Sequence in Physics
- 2 Semester Introductory Sequence in Mathematics plus 1 additional course in Mathematics
- 1 Experimental or Data Analysis Course in Astronomy

The Astronomy Major consists of six core courses in Physics and Mathematics and a laboratory course in Astronomy that are required for every concentration (27-28 credits total), plus additional courses specifically called out to meet the needs of each individual concentration. To enter the major, a student must have completed at least two Physics, and two Mathematics core courses as listed below with a GPA of at least 2.7. To count towards the major, the courses must be taken for letter grade and the minimum grade for any required course is C-. The major is normally entered into after consultation with the Director of Undergraduate Studies (DUS) in astronomy during the student’s fourth semester of work at Cornell. The DUS and student together will also select a suitable faculty advisor in the Field of Astronomy at this time. The required core courses are:

**Three semesters of Physics** including:

In addition to these core requirements, each Astronomy Major must complete a **Concentration** in either **Astrophysics** or **General Astronomy**, which is an additional set of 9-10 courses concentrated in areas relevant to their future career goals.

Astrophysics Concentration

(10 courses, 39 credit hours total)

- 5 additional courses in Physics
- 3 additional courses in Mathematics
- 2 additional courses in Astronomy

The Astrophysics Concentration is designed for those who intend to go on to graduate school in the physical sciences such as Astronomy, Physics, or Engineering. To enter the Astrophysics Concentration, the student must normally have a GPA better than 3.2 in the Astronomy Major Core Courses. The Astrophysics Concentration requires the following additional 10 courses (39 credit hours total):

**Two Semesters of Advanced Astrophysics** selected from two of the three courses in the ASTRO 4431, 4432, 4433 sequence:

ASTRO 4431 (3) | Physics of Stars, Neutron Stars, and Black Holes | |

AEP 4200 (4, Fall) | Intermediate Mathematical Physics |

Course substitutions in the math sequence need to be pre-approved by the DUS.

**Research Experience:**

It is highly recommended that the student with an Astrophysics concentration have at least one semester or one summer research experience under the guidance of a faculty member in the Astronomy Field.

**Course/Credit Count.** The requirements for the Astronomy Major with an Astrophysics Concentration are therefore **16 courses totaling 66-67 credit hours.**

## General Astronomy Concentration

(9-10 courses, 32-33 credit hours total)

- 5 additional courses in Astronomy
- 15 credits in a complementary area of study

The General Astronomy Concentration is designed for students who may not plan on a research career in astronomy, but plan on careers in related fields such as education, or public outreach. The flexibility offered by the General Astronomy Concentration make it suitable to be elected as a second major by a broad group of students. The General Astronomy Concentration requires five additional courses in Astronomy (17-18 credits total), plus an additional 15 credits in an External Concentration (four to five courses) as explicated below.

Five Semesters of Astronomy including **ASTRO 2211** (Stars, Galaxies and Cosmology) and **ASTRO 2212** (The Solar System: Planets, Small Bodies and New Worlds), two of the three courses in the **ASTRO 3301, 3302, 3303** sequence, and one additional astronomy course selected from below:

**ASTRO 2290 (3)** Relativity and Astrophysics

**ASTRO 2299 (3)** Search for Life in the Universe

**ASTRO 3301 (3)** Exoplanets and Planetary Systems

** ASTRO 3302 (3) ** The Life of Stars: From Birth to Death

**ASTRO 3303 (3)** Galaxies Across Cosmic Time

**ASTRO 4445 (4)** Introduction to General Relativity

**ASTRO 4490 (4)** Senior Seminar Critical Thinking

Other Astronomy courses may qualify with prior approval of the DUS.

**Fifteen Credit Hours in Complementary Area.** Complementary Areas can be selected from a wide variety of disciplines, but the courses selected must be cohesive, and complement the core requirements. For example, those interested in astrobiology might chose a Complementary Area of biological sciences, those interested in planetary science might pick Earth and Atmospheric Science, those interested in teaching at the high-school level might pick education, and those interested in public policy might pick Government, Economics, or Science and Technology Studies. It is up to the student, in consultation with their faculty advisor to design the Complementary Area. At least eight of the Complementary Area credits must be in courses numbered above 3000. Complementary Areas are normally mapped out by the end of their sophomore year.

**Course/Credit Count.** The requirements for the Astronomy Major with a General Astronomy Concentration are therefore **16-17 courses** (12 of which are in Astronomy, Physics and Mathematics) **totaling 59-61 credit hours** (44-46 of which are in Astronomy, Physics, and Mathematics).

**Honors**

A student may be granted honors in Astronomy upon the recommendation of the Astronomy Advisors Committee of the Astronomy faculty. Typical requirements for graduating with honors are a minimum GPA of 3.5 over the past four semesters and grades of A– or better in:

(Astrophysics Concentration) ASTRO 4410, ASTRO 4431, and ASTRO 4432 or ASTRO 4433

** or**

(General Astronomy Concentration) ASTRO 4410, ASTRO 3301, ASTRO 3302, ASTRO 3303

**Double Majors**

It is expected that some Astronomy majors, especially those with General Astronomy Concentrations will have double majors, either totally distinct from Astronomy, or ones that include courses from their Complementary Area. In these cases, their Complementary Area credits can be counted for both majors as allowed by the second major. For example, students may double major in Astronomy and Mathematics with the Astronomy Core MATH courses counted towards both majors. However, it is not allowed to double major in Astronomy with an Astrophysics Concentration, and Physics due to extensive overlap of requirements.

## Astronomy Minors Overview

The Astronomy Minors at Cornell University are designed to be flexible so that it can be customized to the needs of each student. There are three concentration paths:
