, 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.

The Flare and Warp of the Young Stellar Disk Traced with LAMOST DR5 OB-type Stars [PDF]
Astrophysical Journal, 2021 We present an analysis of the spatial density structure for the outer disk from 8–14 kpc with the LAMOST DR5 13,534 OB-type stars and observe similar flaring on the north and south sides of the disk, implying that the flaring structure is symmetrical ...

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.

Coherent radio emission from a quiescent red dwarf indicative of star–planet interaction [PDF]
Nature Astronomy, 2020 Low-frequency (ν ≲ 150 MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius.

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 ...

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.
