The weak s-process in massive stars and its dependence on the neutron capture cross sections
The slow neutron capture process in massive stars (weak s process) produces most of the s-

Constraining the astrophysical origin of the p-nuclei through nuclear physics and meteoritic data
A small number of naturally occurring, proton-rich nuclides (the p-nuclei) cannot be made in
the s-and r-processes. Their origin is not well understood. Massive stars can produce p …
