ASTR 143Planets and Exoplanets
Astronomy · 4 units · Undergraduate upper division (100-199)
Designed for upper-division Astrophysics and Physics majors. Focus on detection and characterization of planets orbiting other stars, and on physical processes that determine their formation, structure, and evolution. Topics of discussion include broader astrophysical context of planet formation and how observations of solar system properties can be incorporated into emerging understanding of extrasolar planetary systems.
