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 ...

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.

Microwave observations of red dwarf flare stars
Advances in Space Research, 1986 Abstract We discuss some recent observations of red dwarf flare stars. When observed over periods of about 8 hours, each of 4 flare star systems displayed at least one major flare at 20 cm. Quiescent emission at 6 cm was seen from UV Ceti and EQ Peg A, but flares were much less frequent at 6 cm than at 20 cm. We also summarize earlier observations of

, 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

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,

TESS Observations of Outbursts on Polars—Superflares
The Astrophysical JournalFlare events are magnetic activities on the stellar surface, which can provide us with information about the accretion behavior and evolution of polars. In this paper, we search for flare events on polars from all the available 2 minute cadence TESS data
