  1. What happens if the core is hot enough for fusion?
    • New reactions ignite
    • core size stable
    • shell fusion continues
    • outer layers readjust
  2. What happens when the fuel runs out of the core?
    • Core collapses
    • outer layers escape
  3. Is the core hot enough for fusion?
    • For less than 1/4 solar mass star, never
    • In larger stars, "triple-alpha" process
  4. What happens in the Asymptotic-Giant Branch? Is this the end of the line?
    • The helium fusion dies out; dead carbon core
    • cycle repeats

    • At this point, solar mass star collapses to a white dwarf
    • Outer layers expand as a "planetary nebula"
