Degeneracy occurs when there are not enough quantum states at low velocities, pushing electrons to higher momentum (i.e. velocity) states. From Bohm Vitense Sunday, May 1, 2011
Nuclear Burning: the triple α process 4 He + 4 He -> 8 Be 8 Be+ 4 He -> 12 C q = k ρ 2 T 40 Releasing 7.275 Mev (compared 25 Mev for Hydrogen burning) When enough carbon accumulates: 12 CO + 4 He -> 16 O Releasing 7.162 Mev Sunday, May 1, 2011
