Nucleosynthesis sites in the cosmos
As sites for the nuclear reactions in the cosmos, white dwarfs, core collapsing of stars, proto-neutron star and surface of neutron star are also studied with the mass accretion by binary stars.

Origin of matter and their nuclei abundances in the cosmos
Through the detailed study of sites for r-, s-, rp- and weak processes for the network calculation for nucleosynthesis, we study the nuclear abundances by considering the Galluxy chemical evolution which include a study of the stellar explosion and nucleosynthesis by the cosmic rays.
