Abstract: | The two best-studied subsystems of flare stars, in Orion and the Pleiades, which are of considerably different ages, are compared. It is shown that the observed differences between them are consistent with the evolutionary status of flare stars that represent a stage in the evolution of red dwarfs. It is found that less luminous stars exhibit higher flare frequencies. For equally luminous stars, flare activity is lower in older stars.Translated from Astrofizika, Vol. 37, No. 1, pp. 59–72, January–February, 1994. |
