Supernovae are magnificent astrophysical events that produce neutron stars, black holes and many of the chemical elements necessary for life. However, despite millennia of observations and almost a century of astrophysical study, their explosion mechanism is not yet well understood.
In this talk, I will give an overview over the planned Hyper-Kamiokande experiment, which will observe the neutrino flux from the next galactic supernova in unprecedented detail. By comparing a range of different supernova models, I show that a supernova at up to 100 kpc distance would be sufficient to identify the true model with high accuracy.
Once the next galactic supernova happens, Hyper-Kamiokande will thus be able to determine details of the supernova explosion mechanism.
