Measurement of magnetic field and relativistic electrons along a solar flare current sheet [PDF]
Nature Astronomy, 2020 In the standard model of solar flares, a large-scale reconnection current sheet is postulated to be the central engine for powering the flare energy release1–3 and accelerating particles4–6.

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 ...

Spectral Signatures of Chromospheric Condensation in a Major Solar Flare [PDF]
Astrophysical Journal, 2020 We study the evolution of chromospheric line and continuum emission during the impulsive phase of the X-class SOL2014-09-10T17:45 solar flare. We extend previous analyses of this flare to multiple chromospheric lines of Fe i, Fe ii, Mg ii, C i, and Si ii

INCREASES IN SCR ENERGETIC PROTON FLUXES ON EARTH AND THEIR RELATION TO SOLAR SOURCES
Solar-Terrestrial Physics, 2020 Logachev catalog data for solar cycle 23 has been used to study the dependence of measured increases in solar cosmic rays (SCRs) on solar perturbations. The efficiency of recording the SCR increases, driven by proton acceleration in the corona, on Earth ...
