First Topic
Where do all these elements come from? How are
they made? Are they made?

Nucleosynthesis of the Elements
Why does this happen only in stars?
Hydrogen Burning 1H 1H ? 2H e
ve 2H 1H ? 3He ? 3He 3He ? 4He
21H
41H ? 4He 2e 2ve
18
Helium Burning 4He 4He ? 8Be 8Be 4He ? 12C ?
12C ? 3 4He ? 12C ?
Is this easier or harder than hydrogen burning?
19
Carbon Burning, etc. 12C 4He ? 16O ? 16O
