Glitch modulation period derived from the Kepler data used in Dréau et al. (2021) as a function of Δν, where the stellar mass is colour-coded. Mean error bars estimated for Δν below or above 1 μHz are represented. The thick solid lines are the median values in bins of 0.5 μHz Δν, regardless of the evolutionary stage, shown in blue for low-mass stars (M ≤ 1.2 M_⊙) and in red for high-mass stars (M ≥ 1.2 M_⊙).
