Locations of the flaring giants (big red dots, present paper), dwarfs or stars with an unknown evolutionary status (small red dots, present paper), possible binaries from Table B.1 by Gaulme et al. (2020, dark blue dots), and eclipsing giants with oscillations (light blue dots) oractivity (pink dots) from Gaulme et al. (2016) and Benbakoura et al. (2021) in the Hertzsprung−Russell-diagram. Light blue cross-over red dots mark the flaring and oscillating stars from the present paper. The orange star marks the location of the Sun.
