Radio Emission from Stellar Flares [PDF]
International Astronomical Union Colloquium, 1989 AbstractAn overview is given of the observations of stellar radio ‘flares', defined as radio emission which is both variable in time and created by explosive releases of magnetic energy. The main sources of such flares are late-type Main-Sequence stars, classic close binaries, X-ray binaries, and pre-Main-Sequence stars.We summarize the interpretations

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.

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

A catalogue of white-light flares observed by Yohkoh
, 2003 The aspect camera of the Soft X-ray Telescope (SXT) on Yohkoh provided the first systematic survey of white-light flares from an observatory in space. The observations were made in the Fraunhofer g-band at a pixel size of 2.46 arcsec and a typical sample

Observations and modeling of spectral line asymmetries in stellar flares
, 2023 Context. Stellar flares are energetic events occurring in stellar atmospheres. They have been observed on various stars using photometric light curves and spectra.

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.

Power-law Distribution of Solar Cycle–modulated Coronal Jets
The Astrophysical Journal Supplement Series, 2023 Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted

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.

The Astrophysical Journal Supplement Series, 2022 Stellar parameters and magnetic activity are important for the understanding of stellar physics and dynamo theory. We have used LAMOST spectroscopic surveys to study stellar parameters and magnetic activity properties of TESS objects.
