Optical luminosity light curve of WD–NS mSNe. The left panel shows our fiducial model, assuming an ejecta mass of M_ej = 0.3 M_⊙ and a ⁵⁶Ni mass of M_Ni = 0.01 M_⊙. The right panel presents the WD–NS mSNe model in which both the ejecta and ⁵⁶Ni masses are reduced by an order of magnitude, adopting M_ej = 0.03 M_⊙ and M_Ni = 0.001 M_⊙. Different colors indicate different viewing angles at θ_view = 0°, 15°, 30°, 45°, 60°, and 90°. Solid and dashed lines correspond to the g- and r-band luminosities, respectively.
