Rapid UBVRI photometry of the active flare stars EV Lac and AD Leo

Regular photometric observations of the two active flare stars EV Lac and AD Leo were carried out in 1996--1999. We have compared the location of the intrinsic radiation of the strongest flares in UBVRI two-color diagrams with those predicted by various models for the radiation sources. Our statisti...

Zusammenfassung:Regular photometric observations of the two active flare stars EV Lac and AD Leo were carried out in 1996--1999. We have compared the location of the intrinsic radiation of the strongest flares in UBVRI two-color diagrams with those predicted by various models for the radiation sources. Our statistical analysis of flares in EV Lac confirms the 7.5-year activity cycle reported earlier.
