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 ...
Sleep cycle. The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and wakefulness. In humans, this cycle takes 70 to 110 minutes (90 ± 20 minutes). [1]

The CNO cycle (for carbon – nitrogen – oxygen; sometimes called Bethe–Weizsäcker cycle after Hans Albrecht Bethe and Carl Friedrich von Weizsäcker) is one of the two known sets of fusion reactions by which star s convert hydrogen to helium, the other being the proton–proton chain reaction (p–p cycle), which is more efficient at the ...
El ciclo CNO ( carbono - nitrógeno - oxígeno ), también llamado ciclo Bethe-Weizsäcker a nombre de sus descubridores, es una de las 2 reacciones nucleares de fusión por las que las estrellas convierten hidrógeno en helio, siendo la otra la cadena protón-protón . Aunque la cadena protón-protón es más importante en las estrellas de la ...
