The interest in neutrinos from core collapse supernovae

The understanding of core collapse supernovae (SN) is an important open problem. These objects are intense sources of neutrinos, that can be observed with several types of terrestrial detectors. These two simple considerations, already, motivate close attention toward neutrino interactions in the region from few to 200 MeV. In this work, we offer a selection of results and expectations, and discuss important goals still to be reached.
