Left: evolution of the Galactic SN rate of SNe Iax for a constant star formation rate (Z = 0.02, SFR = 5 M_⊙ yr^-1) in the WD+MS (dash-dotted curve), WD+He star (dotted curve), and WD+RG (thick solid curve) channel. Right: as for the left, but for the single starburst case. Results in the WD+MS channel with the effect of the accretion disk are shown with a thin solid line. For comparison, the results for the double-detonation model (i.e., the Sub-Ch model) from Wang et al. (2013) are also presented with dashed lines.
