r-Process Nucleosynthesis in Shocked Surface Layers of O-Ne-Mg Cores
H. Ning, Y. -Z. Qian, B. S. Meyer
We demonstrate that rapid expansion of the shocked surface layers of an O-Ne-Mg core following its collapse can result in r-process nucleosynthesis. As the supernova shock accelera…
s-Process Nucleosynthesis in Advanced Burning Phases of Massive Stars
Lih-Sin The, Mounib F. El Eid, Bradley S. Meyer
We present a detailed study of s-process nucleosynthesis in massive stars of solar-like initial composition and masses 15, 20,25, and 30 Msun. We update our previous results of s-p…
Are Ti44-Producing Supernovae Exceptional?
L. -S. The, D. D. Clayton, R. Diehl +6
According to standard models supernovae produce radioactive Ti, which should be visible in gamma-rays following decay to Ca for a few centuries. $^{44}Ti production i…
Evolution of Massive Stars Up to the End of Central Oxygen Burning
Mounib F. El Eid, Bradley S. Meyer, Lih-Sin The
We present a detailed study of the evolution of massive stars of masses 15, 20, 25 and 30 $\msun$ assuming solar-like initial chemical composition. The stellar sequences were evolv…
Nucleosynthesis in Fast Expansions of High-Entropy, Proton Rich Matter
G. C. Jordan, B. S. Meyer
We demonstrate that nucleosynthesis in rapid, high-entropy expansions of proton-rich matter from high temperature and density can result in a wider variety of abundance patterns th…
The r-Process without Excess Neutrons
Bradley S. Meyer
The r-process of nucleosynthesis requires a large neutron-to-seed nucleus ratio. This does not, however, that there be an excess of neutrons over protons. If the expansion of the m…
