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.

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.

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 ...

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.

The Astrophysical Journal, 2023 We present light curves and flares from a 7 day, multiwavelength observational campaign of AU Mic, a young and active dM1e star with exoplanets and a debris disk. We report on 73 unique flares between the X-ray to optical data.

The Ultraviolet Radiation Environment Around M dwarf Exoplanet Host Stars [PDF]
, 2012 The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. At present, little observational or theoretical basis exists for understanding the ultraviolet spectra of M ...

Old stellar Galactic disc in near-plane regions according to 2MASS: scales, cut-off, flare and warp [PDF]
, 2002 We have pursued two different methods to analyze the old stellar population near the Galactic plane, using data from the 2MASS survey. The first method is based on the isolation of the red clump giant population in the color-magnitude diagrams and the ...

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 ...

Investigating the Rotational Phase of Stellar Flares on M dwarfs Using K2 Short Cadence Data [PDF]
, 2018 We present an analysis of K2 short cadence data of 34 M dwarfs which have spectral types in the range M0 - L1. Of these stars, 31 showed flares with a duration between $\sim$10-90 min.
