, 2016 We investigate the statistical properties of flare and starspot-induced variabilities of red dwarf stars in the open cluster M37, particularly (1) understanding magnetic activity phenomena that are seen in groups of stars (with the same age and mass) and (2) the correlations among activity indicators.

Flares of Red Dwarf Stars and Solar Activity [PDF]
Symposium - International Astronomical Union, 1975 The UV Cet-type star flares and the chromospheric flares of the Sun have many important common features. Both types of events are very transient; they occupy only small parts of the stellar surfaces; in both cases the optical as well as the radio emissions of the flares have strong similarities in temporal and spectral characteristics.

Detection of a giant white-light flare on an L2.5 dwarf with the Next Generation Transit Survey [PDF]
, 2019 We present the detection of a V ∼ −10 flare from the ultracool L2.5 dwarf ULAS J224940.13−011236.9 with the Next Generation Transit Survey (NGTS). The flare was detected in a targeted search of late-type stars in NGTS full-frame images and represents one

Continuum and line emission of flares on red dwarf stars [PDF]
Astrophysics and Space Science, 2015 The emission spectrum has been calculated of a homogeneous pure hydrogen layer, which parameters are typical for a flare on a red dwarf. The ionization and excitation states were determined by the solution of steady-state equations taking into account the continuum and all discrete hydrogen levels.

Flares on Red Dwarf Stars as a Result of the Dynamical Response of the Chromosphere to the Heating [PDF]
International Astronomical Union Colloquium, 1983 The impulsive hard X-ray, EUV and microwave radio bursts always start at or after the onset of a soft X-ray increase - the main phase of a solar flare - before the Hα flare maximum. This hard phase of a solar flare lasts ~ 100 s and consists of several elementary bursts of 10 s duration.

Time resolved spectroscopic observations of an M-dwarf flare star EV Lac during a flare. [PDF]
, 2016 Flares are explosions on the surface of the Sun and stars. We can find stellar flares frequently on M-dwarf stars. EV Lac, one of the M-dwarf flare stars, is a good target for investigation of stellar flares.

High Time Resolution Photometry of Red Dwarf Flare Stars II. The Shortest Flare Rise Time [PDF]
International Astronomical Union Colloquium, 1989 AbstractWe have studied the initial phases of 65 optical flares on UV Cet type stars with a time resolution of 3x10–7 s. Ninety per cent of these flares have rapid brightenings shorter than 10 s and several are shorter than 1 s. We detected on UV Cet the shortest flare observed to date with a total duration of 1.7 s and a rise time of 0.3 s.

High Time Resolution Photometry of Red Dwarf Flare Stars I. A Search For Fine Structures on the Optical Light Curves of Flares [PDF]
International Astronomical Union Colloquium, 1989 AbstractA detailed analysis of 73 flares on UV Cet type stars observed at the 6 m telescope of the Special Astrophysical Observatory with 3x10–7 s time resolution shows no fine structures on flare light curves with time scales from 10–6 to 10–1 s.
