Abstract Core-collapse supernovae are among the most magnificent events in observable universe. They produce many of chemical elements necessary for life to exist and their remnants—neutron stars black holes—are interesting astrophysical objects own right. However, despite millennia observations almost a century study, explosion mechanism core-collapse is not yet well understood. Hyper-Kamiokande next-generation neutrino detector that will be able observe flux from next galactic supernova...
