Life Cycles of Stars
- birth in cold gas clouds
- main sequence: hydrogen burning; mass-luminosity relation
- brown dwarfs
- helium burning
- intermediate mass stars:
- ejection of planetary nebula: Ring, Cat's Eye
- compact cinder: white dwarf
- high mass stars:
- cycles of contraction and burning
- gravitational collapse of iron core
