Particle acceleration in solar flares with imaging-spectroscopy in soft X-rays
Mitsuo Oka, Amir Caspi, Bin Chen +15
Particles are accelerated to very high, non-thermal energies during explosive energy-release phenomena in space, solar, and astrophysical plasma environments. In the case of solar…
Non-Equilibrium Processes in the Solar Corona, Transition Region, Flares, and Solar Wind \textit{(Invited Review)}
Jaroslav Dudík, Elena Dzifčáková, Nicole Meyer-Vernet +12
We review the presence and signatures of the non-equilibrium processes, both non-Maxwellian distributions and non-equilibrium ionization, in the solar transition region, corona, so…
Hard X-Ray Emission from Partially Occulted Solar Flares: RHESSI Observations in Two Solar Cycles
Frederic Effenberger, Fatima Rubio da Costa, Mitsuo Oka +5
Flares close to the solar limb, where the footpoints are occulted, can reveal the spectrum and structure of the coronal loop-top source in X-rays. We aim at studying the properties…
Kappa Distribution Model for Hard X-Ray Coronal Sources of Solar Flares
M. Oka, S. Ishikawa, P. Saint-Hilaire +2
Solar flares produce hard X-ray emission of which the photon spectrum is often represented by a combination of thermal and power-law distributions. However, the estimates of the nu…
