First Topic Where do all these elements come from? How are they made? Are they made?
Our Guide:
What aspects of this should we explain?
What will our explanations depend on? Thermodynamics: relative stability Kinetics: rate and mechanism
General Decrease in Abundance with Atomic Number
Even > Odd
Peak at Fe
Peak at Pb
Trough at Be
Missing Tc and Pm and Above N = 83
Nucleosynthesis of the Elements Hydrogen Burning 1 H + 1 H 2 H + e + + v e 2 H + 1 H 3 He + 3 He + 3 He 4 He +2 1 H Why does this happen only in stars? 4 1 H 4 He + 2e + + 2v e
Helium Burning 4 He + 4 He 8 Be 8 Be + 4 He 12 C* 12 C + 3 4 He 12 C + Is this easier or harder than hydrogen burning?
Carbon Burning, etc. 12 C + 4 He 16 O + 16 O + 4 He 20 Ne + 20 Ne + 4 He 24 Mg + 12 C + 12 C 24 Mg + 12 C + 12 C 23 Na + 1 H 12 C + 12 C 20 Ne + 4 He Go back to initial Questions. Can we answer any?
The -Process 20 Ne + 16 O + 4 He 20 Ne + 4 He 24 Mg + 2 20 Ne 16 O + 24 Mg + 40 Ca + 4 He 44 Ti* + 44 Ti* + e - 44 Sc* + v + 44 Sc* 44 Ca + + + v + 44 Ca + 4 He 48 Ti +
