Variation in the Flare Frequency of Flare Stars. III. Flare Stars in the Orion Association
Astrophysics, 2002The possible variation of the flare frequency of flare stars in the Orion association is considered. It is shown that of the 23 chosen stars, each having exhibited four or more flares, a change in flare frequency at the 0.1 significance level can be suspected for 13.

Flare periodicity in flare stars?
Astrophysics, 1999Flare periodicity has been found in the flare star Pleiades No. 484. The period of its flare activity is determined from an analysis of the flares’time distribution.

, 1980 Variation of the Flare Frequency of Flare Stars. II. Flare Stars of the Pleiades Cluster
Astrophysics, 2001The possible variation of the flare frequencies of flare stars in the Pleiades cluster is considered. It is shown that of the 75 chosen stars that each exhibit five or more flares, 33 can be suspected of variation of flare frequency at the 0.1 significance level.

The investigation of dMe stars is being continued with the 12-inch visual Zeiss refractor and a new photometer which contains (in increasing distance from the objective) a shutter, a filter slide, a diaphragm slide, a 3-inch focal length Fabry lens, a dark slide, and a General Electric 1P21 photomultiplier tube. The output of the photocell is amplified

The present paper contains an attempt to formulate a theory, based on fast electrons hypothesis, of the chromospheres of flare stars. At the same time we shall undertake a survey of observations on the emission lines of flare stars and comparisons with the theory.
