Abstract
In Knowledge of the proton-proton (p-p) chain and CNO cycle are required for the evolution of main sequence stars during the early formation of the universe. In this study, we summarized the excitation functions of (p,γ) and (p,α) reactions for 7 Be(p,γ)8 B, 12 C(p,γ)13 N, 13 C(p,γ)14 N, 14 N(p,γ)15 O and 15 N(p,α)15 O in p-p chain and CNO cycle using EMPIRE and TALYS computer up to 10 MeV. The calculated data on nuclear fusion cross sections in hydrogen-burning stars were compared with theoretical TENDL-2014 and ENDF/B-VII data from EXFOR. The calculation results show closed agreement between the calculations and the data from literature.
Highlights
Animals, plants, soil, air, planets, stars like everything formed by the basic blocks of matter called atoms
All stars are born from collapsing clouds of gas and dust the interstellar medium (ISM)
The pp chain is more important in stars the mass of the Sun or less and stars of similar mass The CNO cycle by which stars convert hydrogen to helium is the dominant source of energy in more massive stars [5]
Summary
Plants, soil, air, planets, stars like everything formed by the basic blocks of matter called atoms. The p-p fusion is the nuclear fusion process which fuels the Sun and other stars which have core temperatures less than 15×106 K and a reaction cycle at energy of 25 MeV.
