The Flare Catalog and the Flare Activity in the Kepler Mission [PDF]
The Astrophysical Journal Supplement Series, 2019 Abstract We present a flare catalog of the Kepler mission using the long-cadence data of Data Release 25. This catalog comprises 3420 flare stars and 162,262 flare events. A comparison shows that the flare catalogs of previous studies are seriously polluted by various false-positive signals and artifacts.

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Patients' perspectives on flares in knee osteoarthritis: a qualitative study
, 2020 Purpose: Acute flares in osteoarthritis may be an important, although poorly understood part of its natural history. Despite an OMERACT working group recently proposing a preliminary definition of acute flare in OA there is still uncertainty around ...

What aspects of solar flares can be clarified with mm/submm observations?
Frontiers in Astronomy and Space Sciences, 2022 This paper identifies several unsolved questions about solar flares, which can potentially be answered or at least clarified with mm/submm observations with ALMA.

Retrospective analysis of GLEs and estimates of radiation risks
Journal of Space Weather and Space Climate, 2018 28 February 2017 marked 75 years since the first confident registration of solar cosmic rays (SCRs), i.e., accelerated solar particles with energies from about 106 to ~1010 ÷ 1011 eV.

Quasi-Periodic Pulsations in an M-Class Solar Flare
Universe, 2023 We have studied the quasi-periodic pulsations (QPPs) of the M2.3 flare that occurred in the active region NOAA 12172 on 23 September 2014. Through the fast Fourier transform (FFT) method, we decompose the flare light curves into fast- and slowly-varying ...

Universe, 2023 Using the radio spectra of the 2 April 2022 eruptive flare, we analyze a group of highfrequency type III bursts by our new wavelet method. In this analysis, we found a multi-periodicity of these bursts that is interpreted by the electron beams ...
