Description
Supernovae emit their energy mostly as neutrinos. If a galactic supernova occurs, some of thousands of neutrinos are likely to be detected in Super-Kamiokande (SK) for more than a minute. Supernovae have high temperature environments so that beyond standard model particles such as axions are likely to be produced. In this study, we implemented a supernova simulator with the effects of axion-like particles to calculate changes of neutrino emissions. Finally, I will discuss observation of neutrinos from such supernovae in SK.
