Description
Neutrinos from Supernova 1987A (SN1987A) were fundamental in understanding the formation of a newborn neutron star (NS). From an astrophysical perspective, the importance of these neutrinos is that they allowed us to "see" inside the structure of the NS. Approximately 99% of the energy released after the SN1987A explosion was in the form of neutrinos of all species, with equal probability. To study the cooling process of a newborn NS, we simulated neutrinos from SNe using a program created by the Lepton Group at Unicamp, which can be detected by the liquid argon scintillator experiment. We tested the exponential cooling model and estimated the emission temperature and the neutrinosphere radius.
