The origin of both neutron-rich and proton-rich heavy elements has not yet been clearly understood although sixty years have already passed since B2FH (1957). Core-collapse supernova (SN) or binary neutron-star merger (NSM) is undoubtedly a viable candidate site for these heavy elements. We will first discuss the effects of neutrino interactions and oscillations on the r-process and...

The r-process nucleosynthesis has been considered to occur in explosive astronomical phenomena relevant to neutron stars, e.g. core-collapse supernovae and mergers of compact-object (neutron stars/black holes) binaries. However, The detailed quantitative properties in astrophysical models for the r-process are not completely understood yet. In this talk, I will show recent results of r-process...

Enrichment of neutron-rich elements by massive stars and neutron-star mergers in galatic history

Oral Presentation
The data on abundances of neutron-rich elements in metal-poor stars of the Galactic halo and dwarf galaxies are diverse and difficult to interpret. I argue that this is mostly due to the multiple mechanisms producing such elements in the early universe. An additional complication is caused by the mixing of nucleosynthetic products from various sources in the framework of hierarchical structure...
