Relationship between flare area and flare peak temperature T_flare. Flares observed at the Białków Observatory are shown in blue, while data from Howard et al. (2020) are represented in green. The flare from the Shumen Observatory is marked in red (Flare 7). The size of the point indicates the radius of the star on which the flare occurred. The purple and the orange curves, along with their shaded regions, illustrate the power-law fit to our observational data and our observational data combined with the data from Howard et al. (2020) respectively.
