Characteristics of Stellar Flares on EV Lac from a Long-Term Photometric Program

  • Chapter
Magnetodynamic Phenomena in the Solar Atmosphere

Abstract

We present a statistical analysis of a large sample of homogeneous photoelectric monitoring of the red dwarf EV Lac. The data were collected in 10 years at Catania Astrophysical Observatory on Mt. Etna and consist of 175, 90 and 27 flares detected in the U, B and V bands during a total monitoring times of 861, 947, and 826 hours respectively.

The peak luminosity, the total energy emitted, the rise and decay times were determined for each flare. Full report about this work will be found in a forthcoming paper.
