Double-Peaked Flare Events on Red Dwarf Stars and Solar ‘Sympathetic’ Flares [PDF]
Symposium - International Astronomical Union, 1976 About 50% of the flare events observed on red dwarfs are at least double-peaked. As the majority of flare stars are members of double or multiple systems, the possibility that time-overlapping flares originate quasi-simultaneously on the individual components is discussed.Assuming a poissonian occurrence of flares in both components, the expected ...

A Superflare on YZ Canis Minoris Observed by the Seimei Telescope and TESS: Red Asymmetry of Hα Emission Associated with White-light Emission [PDF]
The Astrophysical Journal, 2023 Active M-type stars are known to often produce superflares on the surface. Radiation from stellar (super)flares is important for exoplanet habitability, but the mechanisms are not well understood.

Narrow-band radio flares from red dwarf stars
Astrophysical Journal, 1986 VLA observations of narrow-band behavior in 20 cm flares from two red dwarf stars, L726 - 8A and AD Leo, are reported. The flare on L726 - 8A was observed at 1415 and 1515 MHz; the flux and the evolution differed significantly at the two frequencies. The flare on AD Leo lasted for 2 hr at 1415 MHz but did not appear at 1515 MHz.

Chromospheric lines in red dwarf flare stars. II - EV Lacertae EQ Pegasi A, and V1054 Ophiuchi
Astrophysical Journal, 1984 On presente des observations de profils de raies avec une resolution spectrale de 0,45 A pour trois etoiles M4e semblables, du voisinage solaire, avec une luminosite de 1/60 du Soleil: EV Lacertae, EQ Pegari A et V 1054 Oph. On donne des resultats pour Hα (λ6563), les raies Na D(λλ5890, 5896), He I (λ5876) et les raies triplet infra-rouge Ca II (λλ8498,

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.

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.

A Census of Near-UV M-dwarf Flares Using Archival GALEX Data and the gPHOTON2 Pipeline
The Astrophysical Journal, 2023 M-dwarfs are common stellar hosts of habitable-zone exoplanets. Near-UV (NUV) radiation can severely impact the atmospheric and surface conditions of such planets, making the characterization of NUV flaring activity a key aspect in determining ...
