Abstract
Nuclear astrophysics is an interdisciplinary research field of nuclear physics and astrophysics, seeking for the answer to a question, how to understand the evolution of the universe with the nuclear processes which we learn. We review the research activities of nuclear astrophysics in east and southeast Asia which includes astronomy, experimental and theoretical nuclear physics, and astrophysics. Several hot topics such as the Li problems, critical nuclear reactions and properties in stars, properties of dense matter, r-process nucleosynthesis, and ν-process nucleosynthesis are chosen and discussed in further details. Some future Asian facilities, together with physics perspectives, are introduced.
Highlights
Nuclear astrophysics deals with astronomical phenomena involving atomic nuclei, and it is an interdisciplinary field that consists of astronomy, astrophysics, and nuclear physics
Such an radioactive ion beam facilities (RIB) facility is the laboratory for astrophysics where one can simulate celestial nuclear reactions of astrophysical interest to seek for the origin of atomic nuclides
Follow-up observations of optical-to-infrared light from GW170817, including the contributions of the observations with the Subaru Telescope lead by the J-GEM consortium [242], have provided an evidence that some sort of radioactive nuclei have been produced in binary neutron star merger (NSM)
Summary
Nuclear astrophysics deals with astronomical phenomena involving atomic nuclei, and it is an interdisciplinary field that consists of astronomy, astrophysics, and nuclear physics. Short-lived radioactive nuclei are expected to play the critical roles in explosive nucleosynthesis in stars, galaxies, and the universe Such an RIB facility is the laboratory for astrophysics where one can simulate celestial nuclear reactions of astrophysical interest to seek for the origin of atomic nuclides. We predict a variety of nucleosynthetic products in these explosive episodes as well as quasi-static nuclear burning processes in stars These theoretical predictions motivate spectroscopic astronomical observations of elemental abundances and their distribution in the universe through large scale medium-to-high resolution survey including LAMOSTII, 4MOST, and WEAVE as well as high-dispersion spectrographs equipped on board of ground-based large telescopes like Subaru, Keck, VLT, or TMT and the space telescope like Hubble Space Telescope.
