摘要
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 hares in EV Lac confirms the 7.5-year activity cycle reported earlier. (C) 2000 MAIK "Nauka/lnterperiodica".
