Periods of unstable ℓ = 1 g modes in terms of the effective temperature for the nine flashes experimented by our template low-mass sequence with 0.2025 M_⊙. Color coding indicates the logarithm of the e-folding time (τ_e) of each unstable mode (right scale). Blue numbers at the bottom right corner of each panel indicate the number of the flash, as in Fig. 1. The cyan diamond on the bottom right panel indicates the location of the template model analyzed in Fig. 5 (as in Fig. 1).
