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…
RESIK and RHESSI observations of the 20 September 2002 flare
A. Kepa, R. Falewicz, M. Siarkowski +1
Soft X-ray spectra 3.33 A - 6.15 A from the RESIK instrument on CORONAS-F constitute a unique database for the study of the physical conditions of solar flare plasmas, enabling the…
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…
RESIK Solar X-ray flare element abundances on a non-isothermal assumption
B. Sylwester, K. J. H. Phillips, J. Sylwester +1
Solar X-ray spectra from the RESIK crystal spectrometer on the {\em CORONAS-F} spacecraft (spectral range ~Å) are analyzed for thirty-three flares using a method to derive…
