, 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.

Narrow-band radio flares from red dwarf stars
The 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.

Flaring red dwarf stars: news from Crimea
Uspekhi Fizicheskih Nauk, 1998 Important phenomena are briefly described which have recently been discovered in the Crimean studies of flaring red dwarf stars believed to be the most common type of variable stars in the Galaxy. These phenomena include (i) long-lived radiation from a blueshifted component in the ionized-helium λ 4686 A emission line in the active state of one such ...

Magnetic activity of M dwarf stars from the LAMOST DR10 medium-resolution survey
Astronomy & AstrophysicsAims. M dwarf stars (red dwarfs) are the most common stars in the Milky Way (70$%$ of all stars). Their temperatures and masses are low, but their magnetic activity is strong and includes flares, starspots, and coronal mass ejections.

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.
