Cno Cycle
The proton-proton chain is more important in stars the mass of the sun or less.
Cno cycle. Li after Wiescher et al. This the CNO-II cycle. CNOサイクル CNO cycle とは恒星内部で水素がヘリウムに変換される核融合反応過程の一種である 陽子-陽子連鎖反応が太陽程度かそれ以下の小質量星のエネルギー源であるのに対してCNOサイクルは太陽より質量の大きな恒星での主なエネルギー生成過程である.
Ordinary carbon 12 C serves as a catalyst in this set of reactions and is regenerated. CNO 순환 CNO cycle 문화어. Lautre réaction est la chaîne proton-proton.
The process by which large stars convert elemental hydrogen into helium through a series of nuclear fusion reactions To become a supernova the progenitor star had to be at least eight times our Suns mass so it must have fused hydrogen into helium via the CNO cycle a reaction that uses carbon nitrogen and oxygen as catalysts. In particular there can be carbon C nitrogen N and oxygen O ions.
CNO cycle 説 明 右図に示すように 反応や逆ベータ崩壊核分裂を参照が連鎖したのち 反応によりヘリウムが生成される. These elements and hydrogen react with each other eventually resulting in the same stable Helium-4. Ca 카탈로니아어 de 독일어 el 그리스어 en 영어 es 스페인어 fa 페르시아어 fr 프랑스어 hu 헝가리어 it 이탈리아어 ja 일본어 mk 마케도니아어 no 노르웨이어 ru 러시아어 sv 스웨덴어 tr 터키어.
The CNO cycle for carbonnitrogenoxygen. Sometimes called BetheWeizsäcker cycle after Hans Albrecht Bethe and Carl Friedrich von Weizsäcker is one of the two known sets of fusion reactions by which stars convert hydrogen to helium the other being the protonproton chain reaction p-p cycle which is more efficient at the Suns core temperature. The CNO-II cycle occurs in the Suns core XYZ of the time.
A carbon-12 nucleus captures a proton and emits a gamma ray producing nitrogen-13. The other mechanism of fusion is the carbon-nitrogen-oxygen CNO cycle which involves the next three elements. In the CNO cycle the fusion of hydrogen is catalysed by carbon nitrogen and oxygen and so its rateas well as the flux of emitted CNO neutrinosdepends directly on the abundance of these.
