Bolometric light curve fitting result for SN 2022ngb (red dots). The black solid line stands for the fitting result of the two-component model. Green and blue dashed lines stand for the contribution of the He-rich core and the H-rich shell, respectively. The cyan solid line is the result of the Arnett-like model fitting result. The inset shows the bolometric light curve of SN 2022ngb along with the fitting result up to ∼50 days from explosion.
