Distribution of the found flare populations in the sample stars in the cumulative form (FFD). The sample is binned in mass and period bins as described in Sect. 3.1. The ages are colour-coded from blue to red to yellow for 4.5–800 Myr; field stars with age > 800 Myr are plotted as grey circles. The grey and blue dashed guides corresponding to power law coefficient α = 2.0 and α = 1.5, respectively, for a range of flare energies ∈[10³⁰, 10³⁶] erg in TESS bandpass.
