Nucleosynthesis in massive stars revisited
We have performed the first calculations to follow the evolution of all stable nuclei and their radioactive progenitors in a finely-zoned stellar model computed from the onset of central hydrogen burning through explosion as a Type II supernova. Calculations were done for 15 M⊙, 20 M⊙, and 25 M⊙ Pop I stars using the most recently available set of experimental and theoretical nuclear data, revi...
متن کاملNuclear Aspects of Nucleosynthesis in Massive Stars
Nuclear reactions play a major role not only in the nucleosynthetic processes determining the elemental abundances in the solar system and the Galaxy but also for determining structure and final fate of a star. Massive stars (> 8M⊙) experience a number of burning phases before they explode as type II supernovae after the collapse of the Fe core. Important nuclear reactions in the late burning s...
متن کاملModeling The Nucleosynthesis Of Massive Stars
This overview discusses issues relevant to modeling nucleosynthesis in type II supernovae and implications of detailed studies of the ejecta. After a brief presentation of the most common approaches to stellar evolution and parameterized explosions, the relevance of a number of nuclei to obtain information on the evolution and explosion mechanisms is discussed. The paper is concluded by an outl...
متن کاملNucleosynthesis in Massive Stars Including All Stable Isotopes
We present the first calculations to follow the evolution of all stable isotopes (and their abundant radioactive progenitors) in a finely zoned stellar model computed from the onset of central hydrogen burning through explosion as a Type II supernova. The calculations were performed for a 15M⊙ Pop I star using the most recently available set of experimental and theoretical nuclear data, revised...
متن کاملCommon-Envelope Evolution: the Nucleosynthesis in Mergers of Massive Stars
We study the merging of massive stars inside a common envelope for binary systems consisting of a red supergiant with a mass of 15 – 20M⊙ and a main-sequence companion of 1 – 5M⊙. We are particularly interested in the stage when the secondary, having overfilled its Roche lobe inside the common envelope, starts to transfer mass to the core of the primary at a very high mass-transfer rate and the...
