Query: The light curve in supernova modeled by a continuous radioactive decay
  of $^{56}$Ni   The UVOIR bolometric light curves are usually modeled by the radioactive
decay. In order to model more precisely the absolute/apparent magnitude versus
time relationship the continuous production of radioactive isotopes is
introduced. A differential equation of the first order with separable variables
is solved.
