Fitting of the multiband (UBVgri) early light curves of SN 2021wuf. The light curve of SN 2021wuf compared to the model of Kasen (2010), in which the SN ejecta collide with a nondegenerate binary companion. The dashed lines show the “normal” Type Ia component of this model, the SiFTO template from Conley et al. (2008). The solid lines are CompanionShocking3 + SiFTO template model. The dot indicates real observation value. The horizontal axis represents time relative to the explosion, and the vertical axis represents luminosity.
