CNO bi-cycle | has probability 2% of the energy of our Sun | |
has definition Similar to the CNO cycle, except that it also includes a cycle in which the next-to-last step becomes 15N(p, γ) 16O(p, γ) 17F(β+ν) 17O(p, α) 14N. This reaction occurs once in about 2000 CN cycles. For main-sequence stars greater than a few solar masses, hydrogen burning by the CNO bi-cycle is the main source of energy. | |
