  • While the origin of r-process nuclei remains a long-standing mystery, recent spectroscopic studies of extremely metal poor stars in the Galactic halo strongly suggest that it is associated with core-collapse supernovae. In this study we examine r-process nucleosynthesis in a "prompt supernova explosion" from an 8-10 M☉ progenitor star as an alternative scenario to the "neutrino wind" mechanism, which has also been considered a promising site of the r-process. In the present model, the… CONTINUE READING
