Stars and Star Formation

AST 403/PHY 402

Info tab content
Stars form from interstellar gas, and eventually return material to the interstellar medium (ISM). Nuclear fusion powers stars, and is also the main energy source in the ISM. This course discusses the structure and evolution of the ISM and of stars. Topics include: physical properties and methods for studying ionized, atomic, and molecular gas in the ISM; dynamics of magnetized gas flows and turbulence; gravitational collapse and star formation; the structure of stellar interiors; production of energy by nucleosynthesis; stellar evolution and end states; the effects of stars on the interstellar environment.
