This astrochemistry course is the study of gas phase and solid state chemical processes that occur in the universe, including those leading to pre-biotic compounds. Topics include chemical processes in dying stars, circumstellar gas, planetary nebulae, diffuse clouds, star-forming regions and proto-planetary discs, as well as planets, satellites, comets and asteroids. Observational methods and theoretical concepts will be discussed. Graduate-level requirements include a project and an oral exam. Identical to ASTR 588A; may be convened with ASTR 488A. ASTR is home department.
