The CNO cycle (for carbon - nitrogen - oxygen ), or sometimes Bethe-Weizsäcker-cycle, is one of two fusion reactions by which stars convert hydrogen to helium, the other being the proton-proton chain . The proton-proton chain is more important in stars the mass of the sun or less. Only 1.7% of 4 He nuclei being produced in the Sun are born in ...
CNO-cyklus. I stjerner, som er mere massive end ca. 0,8 solmasser, er kernetemperaturen så høj, at der kan produceres helium i en cyklus af atomare kernefusioner med kulstof, kvælstof og ilt som katalysatorer, den såkaldte CNO-cyklus – Carbon-Nitrogen-Oxygen cyklus . CNO-cyklussen blev foreslået af Hans Bethe i 1938, kun 6 år efter ...
New experimental methods and techniques, combined with the development of new theoretical tools, have opened new avenues to explore nuclear reactions of significance for nucleosynthesis at or near the actual temperatures of stellar burning. In particular, many reactions of the cold and hot CNO cycles have been investigated in recent years to provide a complete understanding of this critical ...
CNO 순환. CNO 순환 ( CNO cycle, 문화어: 탄소 질소 산소 순환)은 항성 이 수소 를 헬륨 으로 변환시키는 핵융합 과정으로서 밝혀진 두 기작 중 하나다 (다른 하나는 양성자-양성자 연쇄 반응 ). pp-연쇄반응과 달리 CNO 순환은 촉매순환 이다. 이론적 모형에 따르면 CNO ...
Niz ugljenik – azot – kiseonik ili CNO niz je jedna od dve reakcije nuklearne fuzije, kojom zvezde pretvaraju vodonik u helijum, a druga je niz proton – proton. Razlika je da je kod CNO niza za nuklearnu fuziju potreban katalizator. Teorija tvrdi da su to procesi koji prevladavaju kod zvezda koji su veće barem 30% od našeg Sunca.

Abstract. Since the independent suggestions in 1938 of Bethe (1939) and von Weiszäcker (1938) that captures of protons by carbon and nitrogen isotopes were the source of energy generation in stars, the CNO cycles have developed into what might be considered by some a many-cycled monster rivalling the many-headed Hydra, However, those of us who ...
