Massive Star Modeling and Nucleosynthesis

After a brief introduction to stellar modeling, the main lines of massive star evolution are reviewed, with focus on nuclear reactions from which gets needed energy counterbalance its gravity. The different burning phases described, as well structural impact they have star. Some general effects uncertainties in reaction rates presented, more precise examples taken 12 C(α, γ) 16 O and sensitivity s -process many rates. changes stars brought by low or zero metallicity reviewed. convection, rotation, mass loss, binarity is effect global nucleosynthetic products stars.
