Title: The final evolution of stars tackled through supernova observations

Abstract: Recent development in transient survey and follow-up programs has been quickly expanding an opportunity to study the nature of stars in the final phase of their evolution and the mechanisms with which stars explode as supernovae (SNe). In this talk, I will introduce our activities in the transient/supernova observations using new instruments/telescopes; a survey using the wide-field Hyper Suprime-Cam (HSC) on the 8.2m Subaru telescope, the Tomoe Gozen project using a wide-filed CMOS camera on the 1.05m Kiso Schmidt telescope, and the SN follow-up program with the new 3.8m Seimei telescope. Some examples are shown for the nature of SNe Ia, a thermonuclear explosion of a white dwarf, from their properties in the first few days, possible origins of calcium-rich transients and peculiar SNe Iax through the follow-up observations, and constraints on the nature and frequency of high-redshift SNe through the HSC survey.
