Bolometric light curves (panel a) and photospheric velocities (panel b) for SNe at points A–F during the pulsation cycle. The explosion of the hydrostatic model is shown for comparison. The inset shows the radius evolution of one pulsation cycle and indicates the points A–F. Once the photospheric temperature drops below 10^3.75 K, the velocities are no longer reliable because SNEC cannot accurately estimate the location of the photosphere due to limitations in low-temperature opacities (Morozova et al. 2015). The complete ϕ-evolution of the light curve and the photometric velocity is available as an online movie.
