Massive stars cause huge explosions called core collapse supernovae(CCSNe) at the end of their evolution. A CCSNe is one of the strongest explosion, which releases 10 percent of the star's mass of the solar in some 10's of seconds. Most of this energy is released as neutrinos.The four fundamental interactions of nature are involved in CCSNe, and CCSNe are complex and difficult to model...

Supernova neutrinos are crucially important to probe the final phases of massive star evolution. As is well known from observations of SN1987A, neutrinos provide information on the physical conditions responsible for neutron star formation and on the supernova explosion mechanism. However, there is still no complete understanding of the long-term evolution of neutrino emission in supernova...

Pre-supernova (pre-SN) neutrinos are emitted from a core of massive stars, which are supposed to be progenitors of core-collapse supernovae (CCSNe). Although it was seemed to be difficult to detect pre-SN neutrinos because of their low energy, detection of pre-SN neutrinos comes into view owing to the recent development of detectors. We believe that future detection of pre-SN neutrinos will...

This talk presents results of a study using Hyper-Kamiokande (HK) to distinguish different supernova models. With $\mathcal{O}(10^5)$ events expected in HK from a supernova near the galactic centre, such a model comparison will allow us to go beyond a simple determination of parameters of the neutrino flux, and to verify assumptions going into current supernova models.

The core collapse of a massive star in the Milky Way will produce a neutrino burst, which will be detected by the Baksan Underground Scintillation Telescope (BUST). The stable and enough low background at the BUST is a clear asset for searching for neutrino bursts. Now two parts of the facility (with the total mass of 242 tons) are used as independent coinciding detectors. Such approach allows...
