    We also review the transition between intermediate-mass and massive stars and the major nuclear and stellar uncertainties involved. Rotation and mass loss both have a strong impact on the evolution and nucleosynthesis in massive stars. The effects of rotation on pre-supernova models are most spectacular for stars between 15 and 25 M ⊙. Big Bang Nucleosynthesis. takes place when the universe is a few minutes old. makes 2H, 3He, 4He and 7Li. Fusion in stars. in stars like the Sun, makes 4He and C, N, O. in massive stars, makes elements up to iron Fusion in supernova explosions. primarily makes elements around iron. Neutron capture in He-fusing stars and supernovae.

      This book contains all of the information on nucleosynthesis in HKT with much more attention paid to shell burning (Prof. Arnett became famous in the s because he was one of the first theoreticians to model shell burning in massive stars) as well as the various s-, r-, and p-process nuclear pathways that occur in massive stars and supernovae. Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions. In sufficiently massive stars, the nucleosynthesis by fusion of lighter elements into heavier ones occurs during sequential hydrostatic burning processes called helium burning, carbon burning, oxygen burning, and silicon burning, in which the ashes of one nuclear fuel become, after compressional heating, the .

      Abstract: In this chapter, after a brief introduction and overview of stellar evolution, we discuss the evolution and nucleosynthesis of very massive stars (VMS: M> solar masses) in the context of recent stellar evolution model calculations. This chapter covers the following aspects: general properties, evolution of surface properties, late central evolution, and nucleosynthesis including Cited by: 4. Massive stars (M * > 8 solar masses) can synthesize helium, carbon, oxygen, neon, magnesium, silicon, sulfur, argon, calcium, titanium, chromium, and iron (and nickel). Elements heavier than iron are made in supernova explosions from the rapid combination of the abundant neutrons with heavy nuclei as well as from the merger of neutron stars.

Nucleosynthesis in massive stars and supernovae, Hardcover – January 1, by William A Fowler (Author)Author: William A Fowler. "Supernovae and Nucleosynthesis" is not a textbook, but it is extremely useful for astronomy students, especially in stellar and chemical evolution.
