Overview:
Understanding the cosmic and galaxy evolution can be achieved by comparisons between observations and theoretical predictions on the production of the heavy nuclei in processes such as r-process elements and chemical evolution driven by astronomical phenomena. Nuclear astrophysics is a key subject covering astronomy, astrophysics, planetary science, nuclear and elementary particle physics, and is still actively growing. Observationally the Subaru telescope has been intensively giving insights on the early generations of stars and dark matter distribution in order to trace the chemical and dynamical evolution of the universe. Pioneering works on unstable nuclei with the RI beam factory at RIKEN also make it possible to study the nucleosynthesis of r-process elements in laboratory systems, which can originate in energetic astrophysical phenomena like supernovae. These results help theoretical investigations on the synthesis of heavy nuclei with the aid of rapid progress in computational power. We, therefore consider it is beneficial to organize this workshop focusing on the r-process to work together with a variety of researchers from theory, observation and experiment. Our goal is to develop a comprehensive picture of the evolution of the universe through the discussion about the cosmic origin of elements and their recycling process, the first generation of astronomical objects, galaxy formation and dynamically driven chemical evolution, formation of solar system, and the origin of life.

Main Topics:
Heavy elements (r/s-process elements) in the universe and the galaxies: origin and distribution
Chemical evolution of the universe, galaxies and stars
Astronomical sites of heavy elements synthesis (Supernovae, GRBs, neutron star binary mergers ,etc.) and their explosion mechanisms
Nuclear reaction caused by quantum beam with hadrons, photons, and neutrinos, and nuclear structure
Nucleo-cosmochronometer and long-life radioactive nuclei
etc.
