New Solar Flare Calcium Abundances with no Surprises: Results from the SMM Bent Crystal Spectrometer
J. Sylwester, B. Sylwester, K. J. H. Phillips +1
The calcium abundance in flare plasmas is estimated using X-ray spectra from the Solar Maximum Mission Bent Crystal Spectrometer (BCS) during the decays of 194 flares (GOES classif…
On the Application of Differential Evolution to the Analysis of X-Ray Spectra
Anna Kepa, Barbara Sylwester, Marek Siarkowski +1
Using methods of differential evolution (DE,) we determined the coronal elemental abundances and the differential emission measure (DEM) distributions for the plasma flaring on 200…
A Multiwavelength Analysis of the Long-duration Flare Observed on 15 April 2002
A. Kepa, B. Sylwester, J. Sylwester +2
We present a multiwavelength analysis of the long duration flare observed on 15 April 2002 (soft X-ray peak time at 03:55 UT, SOL2002-04-15T03:55). This flare occurred on the disk…
The soft X-ray spectrometer polarimeter SolpeX
J. Sylwester, M. Stęślicki, J. Bąkała +15
We present a novel X-ray assembly of functionally related instrument blocks intended to measure solar flare and active region (AR) spectra from within the Russian instrument comple…
Highly ionized Calcium and Argon X-ray spectra from a large solar flare
K. J. H. Phillips, J. Sylwester, B. Sylwester +5
X-ray lines of helium-like calcium (\ion{Ca}{19}) between 3.17~Å and 3.21~Å and associated \ion{Ca}{18} dielectronic satellites have previously been observed in solar flare spectra…
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…
