A Prediction of the Flare Activity of Stellar Aggregates [PDF]
Symposium - International Astronomical Union, 1990 The problem of the statistical prediction of flare activity of a group of flare stars in stellar aggregates is considered.

Stellar Flare Statistics - Physical Consequences [PDF]
International Astronomical Union Colloquium, 1989 AbstractThe observational data permit us to establish clear statistical correlations between different parameters of stellar flare activity and the characteristics of quiet stars. These relations are: (i)between energies and frequencies of flares on stars of different luminosities;(ii)between total radiation energies of flares and quiet stars both in X-

Analysis of Solar-like X-class Flare on Wolf 359 Observed Simultaneously with TESS and XMM-Newton
The Astrophysical Journal, 2023 We present an analysis of a flare on the Wolf 359 star based on simultaneous observations of Transiting Exoplanet Survey Satellite and XMM-Newton. A stellar flare with energy comparable to an X-class solar flare is analyzed on this star for the first ...

Solar and Stellar Flares: Frequency, Active Regions, and Stellar Dynamo
The Astrophysical Journal, 2022 Abstract We demonstrate that for weak flares the dependence of their frequency occurrence on spottedness can be rather weak. The fact is that such flares can occur in both small and large active regions. At the same time, powerful large flares of classes M and X occur much more often in large active regions. In energy estimates, the mean

, 2021 Stellar flares are an important aspect of magnetic activity – from both stellar evolution and circumstellar habitability viewpoints – but automatically and accurately finding them is still a challenge to researchers in the big data era of astronomy.

The Astrophysical Journal, 1982 We study the response of certain spectral signatures of stellar flares (such as Balmer line profiles and the broad-band continuum) to changes in atmospheric structure which might result from physical processes akin to those thought to occur in solar flares.

Probing Non-Thermal Processes in Stellar Flares on AU Mic [PDF]
The role of non-thermal proton energy transportation during solar and stellar flares is largely unknown; greater insight into this physical process will allow us to better understand potential deficiencies in our stellar flare models.

X-ray activity of the RS CVn-type star σ Gem from the first-year observations of the Einstein Probe
Astronomy & AstrophysicsContext. Stellar flares are energetic events driven by the sudden release of magnetic energy in the stellar atmosphere. Compared to the Sun, the diversity of stellar types and environments leads to a richer variety of flaring phenomena.
