DEF

Cycle de réactions thermonucléaires [...] qui réalise globalement la fusion de 4 protons en un noyau d'hélium en partant de la fusion de protons et de noyaux de carbone qui sont régénérés à la fin du cycle. Ce mécanisme de transformation des noyaux d'hydrogène en noyaux d'hélium est prépondérant dans les régions centrales des étoiles plus chaudes que le soleil et constitue l'origine de l'énergie rayonnée par ces étoiles chaudes.
