7 courses with the subject ASTR, each shown exactly as we captured it from the college's catalog, with every element we hold. Where the wording looks broken, that is our reading of the catalog, not the college's text.
ASTR 110Introduction to Astronomy & Lab6
An introduction to current astronomy with an emphasis on how we know what we know. Topics include the solar system; the life cycles of stars; pulsars, quasars, and black holes; and the history and future fate of the universe. No mathematics background beyond high school algebra and trigonometry is assumed. During registration, students will register for both the lecture and a corresponding lab section, which will appear on the student's academic transcript in a single entry. Offered: Fall 2025, Winter 2026 Liberal Arts Requirements: LS, Science with Lab QRE, Quantitative Reasoning Tags: CL: 100 level Faculty: Ryan Terrien · Andreia Carrillo
Theory and practice of basic techniques in observational and laboratory astronomy. Certain problems involve the use of the 16-inch and 8-inch telescopes. Offered: Fall 2025, Spring 2026 Grading: S/CR/NC Liberal Arts Requirements: LS, Science with Lab QRE, Quantitative Reasoning ASTR 127 or ASTR 232 or ASTR 233 or PHYS 228 or PHYS 232 or PHYS 233 with a grade of C- or better.

ASTR 222A Survey of Cosmology
A detailed survey of selected topics in cosmology. Topics might include the Friedmann equation, fluid and acceleration equations, basic metrics, evolution of single and multi-component universes, cosmological parameters, dark matter, baryogenesis/leptogenesis, the cosmic microwave background radiation, nucleosynthesis, inflation, and structure formation. All topics will be covered assuming only intro level physics as prerequisite. Sophomore Priority section is available Offered: Spring 2026 Credits: 6
A study of stellar structure and evolution with an emphasis on the physical principles underlying the observed phenomena. Topics include the birth, evolution, and death of stars, pulsars, black holes, and white dwarfs. Offered: Spring 2026 Liberal Arts Requirements: No Exploration QRE, Quantitative Reasoning PHYS 144 or PHYS 151 AND PHYS 228 or PHYS 231 with a grade of C- or better.

ASTR 294Directed Research in Astronomy1
Students work on a research project related to a faculty member's research interests, and directed by that faculty member. Student activities vary according to the field and stage of the project. The long-run goal of these projects normally includes dissemination to a scholarly community beyond Carleton. The faculty member will meet regularly with the student and actively direct the work of the student, who will submit an end-of-term product, typically a paper or presentation. Offered: Fall 2025, Winter 2026, Spring 2026 – 6
