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.

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

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-

X-ray/H$\alpha$ scaling relationships in stellar flares

, 2023
We report on the results of our simultaneous observations of three large stellar flares with soft X-rays (SXRs) and an H$\mathrm{\alpha}$ emission line from two binary systems of RS CVn type.

Study of stellar flares [PDF]

, 2014
Kepler observations revealed that many sun-like stars produce flares that are much greater strength in terms of total luminosity visual wavelengths compared to solar flares.

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

Models for stellar flares

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.

A 7 Day Multiwavelength Flare Campaign on AU Mic. I. High-time-resolution Light Curves and the Thermal Empirical Neupert Effect

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.
