Lecture 16: The Evolution of Low-Mass Stars
What happens to a low-mass star (less than 4 solar masses) when\nit runs out of core Hydrogen and must leave the Main Sequence.\nThis lecture describes the changes inside a low-mass star after\nHydrogen exhaustion through the Red Giant, Horizontal Branch,\nAsymtotic Giant, and Planetary Nebula phases. In the end, we will\nsee the star's envelope and core go their separate ways, the\nenvelope gently puffed off into space, briefly flowering as a\nPlanetary Nebula, and the Carbon-Oxygen core collapsing into\na White Dwarf.\nRecorded 2006 January 26 in 1008 Evans Laboratory on the Columbus campus\nof The Ohio State University.
