Scientific paper

In this paper, we present a new method for determining the temperature and ionization evolution of the hydrogen envelope of SN 1987A by comparing the observed H alpha light curve and one which is derived from the recombination theory for hydrogen lines. This is a simple and convenient method for determining the temperature and ionization evolution which could be applicable to the late time of all Type II supernovae.
