      Introductory of Nuclear Astrophysics 1h 30m

      Our universe has begun about 13.7 billion years ago with Big Bang, and developed through variety of phenomena till the present, our rich world now. To learn the mechanism of the evolution of the universe as well as various phenomena requires scientific efforts from many fields. Visible matters of the universe are made of elements of about 100 species which were also produced along the evolution of the universe. Nuclear reactions produce new elements as well as anomalous energies, and play a key role in various stellar phenomena along the evolution. Nuclear physics study together with observations of elements as well as neutrinos and photons of various wave-lengths opens up a new scope to understand “our universe”.

      Astronomical Observations. 1. Stellar chemical compositions to constrain nucleosynthesis in the universe 1h 30m

      Chemical compositions of variety types of stars contain useful information to constrain the nucleosynthesis in the universe. The products of nuclear reactions inside stars sometimes appear at the surface of highly red giants in the very late stage of stellar evolution. On the other hand, most of stars before that, including the Sun as a main-sequence star, preserve compositions of elements provided by the previous generations of stars and supernova explosions. In this lecture, I present some examples of studies of stellar chemical compositions to constrain nucleosynthesis in stars and supernovae. The methods to determine elemental and isotopic abundances of stars are also presented.

      Astronomical Observations. 2. Novae and r-process 1h 30m

      This lecture provides overview of recent progress in understanding of explosive nucleosynthesis of Li and heavy elements. Recent observations have revealed that nova explosions are major source of Li in the Galaxy. Observational methods and results of novae are presented. The astrophysical site of the r-process that is a major source of elements heavier than iron in the universe is a longstanding problem. The detection of gravitational wave and follow-up optical observations have identified the merger of binary neutron stars to be a site of the r-process. Spectroscopic observations of early generations of stars also give useful constraints on the nature of the r-process. Current understanding of the r-process based on observational results is reviewed.

      Nuclear Astrophysics and Cosmology I: Big-Bang cosmology 1h 30m

      My course lectures will cover the basics and fundamentals in nuclear astrophysics and cosmology. The ultimate goal is to explore what we are made of, why and how the universe began and evolved, and whether we are alone in the universe. For this goal I will lecture on nuclear physics in explosive nucleosynthesis in the Big-Bang universe, supernovae and neutron star mergers. In the near future, humans will surely develop their activities in space. We need to be prepared by studying how and when the atomic nuclei that make up our life were created, and what important roles they have played so far in the evolution of the universe, galaxies, and stars.
