Astrophys. 327 1114 1997 1997A&A...327.1114L Photometry, UBV Stars, flare stars: activity stars: flare stars: individual (EV Lac) stars: rotation We report on a large sample of homogeneous photoelectric data obtained by monitoring the red dwarf flare star EV Lac. The data were collected in 10 years (1967-77) at Catania Astrophysical Observatory on Mt. Etna. The peak luminosity, the total energy emitted, the rise and decay times were measured for each flare.
