Periodicity of the Flare Frequency of Flare Stars

Astrophysics, 2019
Data from the Kepler Orbital Observatory are used in a statistical study of the periodic/cyclical variability of the flare frequency of 76 flare stars. Corresponding periodic functions of the flare frequency are obtained and a possible periodicity of the flare frequency with a period equal to the star’s rotation period is tested.

Cyclic flaring activity of flare stars

Astrophysics, 2010
Methods of detecting probable cycles in the flaring activity of flare stars and determining the cycle durations are examined. A new method of detecting a cycle of flaring activity and determining its duration is proposed assuming periodic flaring activity.

A Search for Flare Stars

Publications of the Astronomical Society of the Pacific, 1955
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

Chromospheres of flare stars

Astrophysics and Space Science, 1977
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.
