Dependence of the bolometric light curve and the mass fractions at t = 50 days on the explosion energy for the late-time 1D simulations with the representative radioactive 56Ni mass from Table 2. Panel a): light curves of models B15-1 (green solid line), B15-2 (blue solid line), and B15-3 (magenta solid line) compared with the observations of SN 1987A obtained by Catchpole et al. (1987, 1988) (open circles). The light curves of the corresponding models without radioactive 56Ni are shown with dotted lines. Panels b)d): mass fractions as functions of velocity in models B15-1, B15-2, and B15-3, respectively. The red line is the mass fraction of radioactive 56Ni, and the magenta line represents iron-group elements except for 56Ni (see also Fig. 2).
