| Outline of Final Research Achievements |
We investigate the evolution of various massive stars such as stars with the initial mass of 10-20 solar-mass, very massive stars, and CO stars supposing a star evolved in a close binary system. We apply the calculated evolved stars to various supernova models. Then, we investigate the relation between a variety of SNe recently observed and the massive stars. We also investigate the observational possibility of presupernova neutrinos from future nearby supernovae. The observations of presupernova neutrinos would reveal the evolution of the internal structure of a massive star just before the supernova explosion. We will release the database of the structure and composition of the presupernova stars.
