Cold Solar Flares I. Microwave Domain
Alexandra L. Lysenko, Stephen M. White, Dmitry A. Zhdanov +4
We identify a set of ~100 "cold" solar flares and perform a statistical analysis of them in the microwave range. Cold flares are characterized by a weak thermal response relative t…
Twin Null-Point-Associated Major Eruptive Three-Ribbon Flares with Unusual Microwave Spectra
V. V. Grechnev, N. S. Meshalkina, A. M. Uralov +7
On 23 July 2016 after 05:00\,UTC, the first 48-antenna stage of the Siberian Radioheliograph detected two flares of M7.6 and M5.5 GOES importance that occurred within half an hour…
Rapid Variability in the SOL2011-08-04 Flare: Implications for Electron Acceleration
Alexander T. Altyntsev, Nataliia S. Meshalkina, Alexandra L. Lysenko +1
Particle acceleration in solar flares remains an outstanding problem in solar physics. It is yet unclear which of the acceleration mechanisms dominates and how exactly is the exces…
Microwave Signature of Relativistic Positrons in Solar Flares
Gregory Fleishman, Alexander Altyntsev, Nataliia Meshalkina
Relativistic antiparticles can be created in high-energy nuclear interactions; thus, detection of antiparticles in an astrophysical source can tell us something remarkable about th…
Thermal to Nonthermal Energy Partition at the Early Rise Phase of Solar Flares
Alexander A. Altyntsev, Gregory D. Fleishman, Sergey V. Lesovoi +1
In some flares the thermal component appears much earlier than the nonthermal component in X-ray range. Using sensitive microwave observations we revisit this finding made by Batta…
