Flare Stars in Star Clusters and Associations [PDF]
Symposium - International Astronomical Union, 1975 The study of stellar evolution can be undertaken either from a purely theoretical point of view or from a more observational approach. The present standpoint is the second one. It starts from the concepts of stellar evolution in associations and open clusters and from stellar flare activity.

Spots and Flares in Hot Main Sequence Stars Observed by Kepler, K2, and TESS
Frontiers in Astronomy and Space Sciences, 2021 About 22,000 Kepler stars, 7,000 K2 stars, and nearly 60,000 TESS stars from sectors 1–24 have been classified according to variability type. A large proportion of stars of all spectral types appear to have periods in their light curves consistent with ...

Flare stars at radio wavelengths [PDF]
Symposium - International Astronomical Union, 1990 The radio emission from dMe flare stars is discussed using Very Large Array and Arecibo observations as examples. Active flare stars emit weak, unpolarized, quiescent radio radiation that may be always present. Although thermal bremsstrahlung and/or thermal gyroresonance radiation account for the slowly-varying, quiescent radio radiation of solar ...

Magnetic activities and parameters of 43 flare stars in the GWAC archive
, 2022 In the archive of the Ground Wide Angle Camera (GWAC), we found 43 white light flares from 43 stars, among which, three are sympathetic or homologous flares, and one of them also has a quasi-periodic pulsation with a period of $13.0\pm1.5$ minutes. Among

Properties of Flare Quasiperiodic Pulsations Based on a New TESS Flare Catalog
The Astrophysical Journal Supplement SeriesStellar flares are important indicators of stellar magnetic activity and have been widely studied. Detailed studies of flares have raised new questions. For example, the quasiperiodic pulsation (QPP) phenomenon in flares challenges standard flare models,

Probability Distribution Functions of Solar and Stellar Flares
Physics, 2022 The paper studies the soft X-ray data of solar flares and found that the distribution functions of flare fluence are successfully modeled by tapered power law or gamma function distributions whose power exponent is slightly smaller than 2, indicating ...

Magnetic Activity of TESS Objects Observed in the LAMOST Medium-resolution Spectral Survey
The Astrophysical Journal Supplement SeriesA combination of spectroscopic and photometric observations provides an excellent data sample for studying stellar chromospheric activity. We have combined LAMOST medium-resolution spectra with TESS 2 minute light curves and extracted over 530,000 ...

The Astrophysical Journal, 2009 Two large X-ray flares have been reported from the direction of a magnetic B2p star (σ Ori E). Sanz-Forcada et al. have suggested that the flares did not occur on the B2p star but on a companion of late spectral type. A star which is a candidate for a late-type flare star near σ Ori E has recently been identified by Bouy et al.
