Evolution of Flare Activity in GKM Stars Younger Than 300 Myr over Five Years of TESS Observations [PDF]
The Astronomical JournalStellar flares are short-duration (< hours) bursts of radiation associated with surface magnetic reconnection events. Stellar magnetic activity generally decreases as a function of both the age and Rossby number, R _0 , a measure of the relative ...

Flare Activity and Magnetic Feature Analysis of the Flare Stars. III. K-type Dwarf Binary Components
The Astrophysical JournalWe analyze the light curve of 199 dwarf stars that are members of binary systems resolved by Kepler mission. All of them are K-type active stars in binary systems of which their flare activity has been confirmed.

Temporal Variation of Flare Occurrence Rates via the Spot Evolution on the Sun and Solar-type Stars
The Astrophysical JournalThe spot evolution on the Sun and solar-type stars is important for understanding the nature of consequential flaring activity. This study statistically investigates the variance of flare occurrence rate through the time evolution of spots on the Sun and

The White-light Superflares from Cool Stars in GWAC Triggers [PDF]
The Astrophysical JournalM-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the GWAC, with flare energies ranging from 10 ^32.2

A Statistical Study of Soft X-Ray Flares on Solar-type Stars [PDF]
The Astrophysical Journal, 2023 The statistical characteristics of stellar flares at optical bands have received extensive study, but they remain to be studied at soft X-ray bands, in particular for solar-type stars.

An “A star” on an M star during a flare within a flare [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractM dwarfs produce explosive flare emission in the near-UV and optical continuum, and the mechanism responsible for this phenomenon is not well-understood. We present a near-UV/optical flare spectrum from the rise phase of a secondary flare, which occurred during the decay of a much larger flare.

Flare stars in nearby Galactic open clusters based on TESS data [PDF]
, 2021 The study is devoted to search for flare stars among confirmed members of Galactic open clusters using high-cadence photometry from TESS mission. We analyzed 957 high-cadence light curves of members from 136 open clusters.

Spectral Observations of Flare Stars [PDF]
Symposium - International Astronomical Union, 1990 Spectral observations of 6 flare stars in the Pleiades cluster are carried out which occupy different positions on the Hertzsprung-Russell diagram relative to the main sequence: above and below it. The spectral indices which are sensible to luminosity or temperature of the star photosphere are determined.
