    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 stars convert hydrogen to helium, the other being the proton–proton chain reaction (p-p cycle), which is more efficient at the Sun's core temperature.

  4. Negli anni seguenti, furono aggiunti molti dettagli alla teoria di Bethe, come un famoso articolo del 1957 pubblicato da Margaret Burbidge, Geoffrey Burbidge, William Fowler e Fred Hoyle. Tale articolo riassumeva e rifiniva le ricerche precedenti in una visione coerente che era consistente con le abbondanze osservate degli elementi.

  5. Hans Bethe realized that a proton smashing into another proton with enough force could be the reaction to power the Sun. In 1938, Bethe and his colleagues presented a fully developed proton-proton chain of reactions that converts hydrogen into helium, which would allow the Sun to shine for about 10 billion years.

  6. 03/04/2020 · In the 1930s, German-American astronomer Hans Bethe showed that nuclear reactions are what power our Sun and all other stars. His work described how the Sun uses nuclear fusion to turn hydrogen ...
