| Outline of Final Research Achievements |
To study the properties of massive stars just before the supernova explosion, we have performed high-cadence optical transient surveys. With the Subaru telescope and a wide field camera (Hyper Suprime-Cam), we have discovered luminous, rapidly rising transients, and suggested that some massive stars experience intensive mass loss just before the explosion. We have also developed a multi-dimensional, time-dependent, wavelength-dependent radiative transfer simulation code to give the direct comparison between supernova models and observations.
