A self-maintaining CNO chain starts at approximately 15 × 106 K, but its energy output rises much more rapidly with increasing temperatures [1] so that it becomes the dominant source of energy at approximately 17 × 106 K. [4] The Sun has a core temperature of around 15.7 × 106 K, and only 1.7% of 4. He.
25. Nov. 2020 · The CNO cycle is thought to be the primary mechanism for the stellar conversion of hydrogen into helium in the Universe and is estimated to account for 1% of energy production in the Sun;...
25. Nov. 2020 · They have detected solar neutrinos produced by a cycle of nuclear-fusion reactions known as the carbon–nitrogen–oxygen (CNO) cycle. Measurements of these neutrinos have the potential...

25. Nov. 2020 · NATURE PODCAST. 25 November 2020. Neutrinos give insights into the workings of the Sun’s core. Scientists have finally confirmed the existence of a CNO cycle fusion reaction in the Sun, and...
25. Nov. 2020 · 25.11.2020. Wissenschaftlerinnen und Wissenschaftler der Borexino-Kollaboration haben den ersten experimentellen Beweis für das Auftreten des sogenannten CNO-Zyklus in der Sonne erbracht: Sie konnten charakteristische Neutrinos, die bei diesem Fusionsprozess entstehen, direkt beobachten.
26. Nov. 2020 · Dem Forschungsteam des Borexino-Experiments ist es zum ersten Mal gelungen, Neutrinos aus dem zweiten Fusionsprozess der Sonne, dem Carbon-Nitrogen-Oxygen-Zyklus (CNO-Zyklus), nachzuweisen. Damit sind nun alle theoretischen Vorhersagen über die Energieerzeugung im Inneren der Sonne auch experimentell bewiesen.
25. Nov. 2020 · 25 November 2020. Scientists who are members of the Borexino Collaboration have provided the first experimental proof of the occurrence of the so-called CNO cycle in the Sun: They have managed to directly detect the distinctive neutrinos generated during this fusion process.
