| Outline of Final Research Achievements |
We have studied explosion sites of supernovae observationally. We found that there are two groups of Type Ia supernovae (SNeIa) based on luminosity-color distributions, depending on their host properties (color). We also found a SNIa on a S0 galaxy, whose explosion was ignited with He detonation.
We have studied equivalent widths of Halpha and metalicity of explosion sites of Core Collapse SNe statistically. But we could not find significant differences amoung different types of SNe.
We updated a CCD of Kyoto3DII IFU spectrograph, and carried out spectroscopy of a host galaxy of a Fast Radio Burst. We also updated CCDs of a 15-band optical simultaneous imager DMC.
