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 ...

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.

Coronal Response to Magnetically Suppressed CME Events in M-dwarf Stars [PDF]
Astrophysical Journal, 2019 We report the results of the first state-of-the-art numerical simulations of coronal mass ejections (CMEs) taking place in realistic magnetic field configurations of moderately active M-dwarf stars.

Origin of the Blue Continuum Radiation in the Flare Spectra of dMe Stars [PDF]
Astrophysics, 2016 Calculations of the emission spectrum of a homogeneous plane layer of pure hydrogen plasma taking into account nonlinear effects (the influence of bremsstrahlung and recombination radiation of the layer itself on its Menzel factors) show that the Planck ...

Living with a Red Dwarf: FUV & X-ray emissions of dM stars and effects on hosted Planets [PDF]
, 2009 Red Dwarf (dM) stars are overwhelmingly the most numerous stars in our Galaxy. These cool, faint and low mass stars make up more than 80% of all stars. Also dM stars have extremely long life times (longer than 50-100 Gyr).

Hot DAVs: a probable new class of pulsating white dwarf stars [PDF]
, 2013 We have discovered a pulsating DA white dwarf at the lower end of the temperature range 45 000–30 000 K where a few helium atmosphere white dwarfs are known. There are now three such pulsators known, suggesting that a new class of theoretically predicted

, 1966 Acoustic waves, hydromagnetic effect, and convective instability due to molecular dissociation are considered as mechanisms for flare activity in M dwarf stars. The first mechanism does not appear to be significant.

Some results of the coordinated observations of the red dwarf flare star EV Lac in 1986–1994 [PDF]
International Astronomical Union Colloquium, 1995 In 1986-94 a series of coordinated monitorings for the flare star EV Lac has been performed. The observations were aimed to collect homogeneous data on the star both in its active and quiet states, to study its flares and starspots. These photometric patrols were accompanied by monitorings of EV Lac of different other kinds: polarimetric, spectral ...
