Simple fits for the neutrino luminosities from protoneutron star cooling

Giuseppe Lucente, Malte Heinlein, H. -Thomas Janka +1

We propose a simple fit function, $L_{{\nu }_i}(t)=C{t}^{-\alpha }{e}^{-(t/\tau {)}^n}$, to parametrize the luminosities of neutrinos and antineutrinos of all flavors during the protoneutron…
