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 ...

Symposium - International Astronomical Union, 1995 Formation of the flare stars database (FSDB) continues (Tsvetkov et al. 1993). Since the beginning of systematic monitoring up to the present 1608 flare stars have been discovered with more than 3107 flare events observed for more than 9313 hours. (Repeated flares for stars from the solar neighbourhood, as well as the time used for their monitoring ...

M Dwarf Flares from Time-Resolved SDSS Spectra
, 2010 We have identified 63 flares on M dwarfs from the individual component spectra in the Sloan Digital Sky Survey using a novel measurement of emission line strength called the Flare Line Index.

White-light flares on cool stars in the Kepler Quarter 1 Data
, 2010 We present the results of a search for white light flares on the ~23,000 cool dwarfs in the Kepler Quarter 1 long cadence data. We have identified 373 flaring stars, some of which flare multiple times during the observation period.

Stellar flares observed in long cadence data from the Kepler mission
, 2017 We aim to perform a statistical study of stellar flares observed by Kepler. We want to study the flare amplitude, duration, energy and occurrence rates, and how they are related to the spectral type and rotation period.

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,

Deep XMM-Newton observation of the Eta Chamaleontis cluster
, 2010 The members of the Eta Chamaleontis cluster are in an evolutionary stage in which disks are rapidly evolving. It also presents some peculiarities, such as the large fraction of binaries and accretion disks, probably related with the cluster formation ...

Arthritis Care &Research, EarlyView.Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

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 ...
