Elements in the Universe and Galactic Chemical Evolution
9 units (3-0-6)  | second term
Prerequisites: Ay 121, 123, 124, 126.

Survey of the formation of the elements in the universe as a function of cosmic time. Review of the determination of abundances in stars, meteorites, H II regions, and in interstellar and intergalactic gas. Overview of models of galactic chemical evolution. Participants will measure elemental abundances from the Keck spectrum of a star and construct their own numerical chemical evolution models. Not offered 2022-23.
