  journal={The Astrophysical Journal},
We present a comprehensive study of s-process nucleosynthesis in 15, 20, 25, and 30 M☉ stellar models having solar-like initial composition. The stars are evolved up to ignition of central neon with a 659 species network coupled to the stellar models. In this way, the initial composition from one burning phase to another is consistently determined, especially with respect to neutron capture reactions. The aim of our calculations is to gain a full account of the s-process yield from massive… Expand
s-Process Nucleosynthesis in Advanced Burning Phases of Massive Stars
It is shown that the recent compilation of the 22Ne(α,n)25Mg rate leads to a remarkable reduction of the efficiency of the s-process during core He burning, which leads to the lowest overproduction factor of 80Kr found to date duringcore He burning in massive stars. Expand
The s-Process Nucleosynthesis in Massive Stars: Current Status and Uncertainties due to Convective Overshooting
Context: It is well known that the so-called s-process is responsible for the production of neutron-rich trans-iron elements, that form the bulk of the "heavy nuclides" (i.e. nuclides more massiveExpand

The Dawes Review 2: Nucleosynthesis and Stellar Yields of Low- and Intermediate-Mass Single Stars
Abstract The chemical evolution of the Universe is governed by the chemical yields from stars, which in turn are determined primarily by the initial stellar mass. Even stars as low as 0.9 M⊙ can, atExpand
Non-standard s process in low metallicity massive rotating stars
Context. Rotation is known to affect the nucleosynthesis of light elements in massive stars, mainly by rotation-induced mixing. In particular, rotation boosts the primary nitrogen production. ModelsExpand

The effect of 12C +12C rate uncertainties on the evolution and nucleosynthesis of massive stars
