High-Resolution Solar X-ray Spectroscopy from Archived Solar Maximum Mission Data
Kenneth J. H. Phillips, Barbara Sylwester, Janusz Sylwester
Archived high-resolution X-ray spectra in the 13~Å to 22~Å range from the Flat Crystal Spectrometer (FCS), an instrument on the Solar Maximum Mission operating in the 1980s, are an…
Varying Calcium Abundances in Solar Flares seen by Solar Maximum Mission
Barbara Sylwester, Janusz Sylwester, Kenneth J. H. Phillips +1
We report on calcium abundance estimates during the decay phases of 194 solar X-ray flares using archived data from the Bent Crystal Spectrometer (BCS) on Solar Maxim…
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…
