The CNO Cycle
						• Gives way around need for p n during the collision • Still must happen later – but don’t need to rare events simultaneously • Trade off is need for higher energy collisions  (T>16 million K) • Add p to some nucleus where new one is still “stable” • Wait for p  n while that nucleus just “sits around” • The net effect is still   4  1H   4He • C just acts like a “catalyst”
