Analysis of Solar-like X-Class Flare on Wolf 359 Observed Simultaneously with TESS and XMM-Newton

Małgorzata Pietras, Robert Falewicz, Marek Siarkowski +3

We present an analysis of a flare on the Wolf 359 star based on simultaneous observations of TESS and XMM-Newton. A stellar flare with energy comparable to an X-class solar flare i…

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…

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…

X-ray Flare Spectra from the DIOGENESS Spectrometer and its concept applied to ChemiX on the Interhelioprobe spacecraft

J. Sylwester, Z. Kordywski, S. Plocieniak +12

The {\em DIOGENESS} X-ray crystal spectrometer on the {\em CORONAS-F} spacecraft operated for a single month (25~August to 17~September) in 2001 but in its short lifetime obtained…
