Determination of the age of stellar aggregates and flare stars of the galactic field

Astrophysics Aims and scope

Abstract

On the basis of the relationship between the age and the magnitude of the maximal flare amplitude in flare stars found previously by the author we propose a method of determining the age of aggregates. Using new observational data relative to flares in U and B we determine the age of the Cyg T1 association (3.4 · 10 6 years), which differs only slightly from an earlier estimate. We give estimated upper bounds for the ages of some flare stars in the solar neighborhood: UV Ceti, EV Lac, AD Leo, EG Peg, and YZ CMi, and also for seven flare stars of the galactic field. It follows from these results that the ages vary noticeably.
