Nukleosynthese
Web1 nov. 1995 · Presupernova models and nucleosynthesis in massive stars are reviewed in the context of supernovae. First, presupernova evolutionary models of massive stars toward the onset of collapse from 13 to 70 M⊙ stars in the main-sequence stage are presented. It is stressed that silicon (“Si”) shell burning is the key point to determine the … WebAt the end of a massive star's life, or if a smaller mass stellar remnant accretes enough mass, it may encounter a powerful explosion -- a supernova -- and eject most or all of the ashes of preceding nuclear burning stages back into space, yet its composition modified by the explosion itself. These supernovae are the main source of oxygen and heavier …
