Abstract

For the very first time, in 1987, modern astronomy was able to witness a core-collapse Supernova (SN1987A), located in the Large Magellanic Cloud (LMC) galaxy. Among many subjects in the event to be studied by astrophysics and other fields, research regarding neutrino emissions and star collapses have advanced considerably after the supernova. At that day, there were many neutrino detectors on Earth which have measured neutrino interactions events almost at the same time, approximately two hours before even visible light could reach us. Alongside Pontecorvo's studies on neutrino oscillations, we will be able to make a connection between these particles and the astronomical event that sets the end of star evolution, which has a close connection with neutrinos since these they are behind of approximately 99\% of the total gravitational binding energy released in the event by all the three flavors.
