Smith College A calculus-based introduction to the properties, structure, formation and evolution of stars and galaxies. The laws of gravity, thermal physics and atomic physics provide a basis for understanding observed properties of stars, interstellar gas and dust. We apply these concepts to develop an understanding of stellar atmospheres, interiors and evolution, the interstellar medium, and the Milky Way and other galaxies. Prerequisites: two semesters of college-level physics (concurrent enrollment is acceptable) and second-semester calculus. 4 credits.
