The book's treatment of Stellar Structure & Evolution is spread
across Chapters 20-24. I am adopting a different path through this
fascinating topic than the book's. See the individual lectures for
specific readings (expect to be reading specific sections, or skipping
the book altogether for some lectures).
Unit 3: Endpoints of Stellar Evolution
Chapter 22 sections 6-8, parts of Chapters 23 & 24
Unit 4: The Milky Way & the Galaxies
Chapters 25, 26, parts of Chapter 27
Unit 5: The Evolving Universe
Chapter 24, sections 1 & 2, Chapter 28, parts of Chapter 29
Unit 6: Frontiers of Modern Astronomy
None, but browse Chapter 30. Some interesting web articles may be
assigned if I come across any I like.
