Emission Measures Demystified
Brian R. Dennis, Kenneth J. H. Phillips
We review the terms, spectral radiance and spectral irradiance, and show how their precise definitions are crucial for interpreting observations made with different instruments cov…
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…
Detection of the third innermost radiation belt on LEO CORONAS-Photon satellite around 2009 solar minimum
Oleksiy V. Dudnik, Janusz Sylwester, Miroslaw Kowalinski +2
We analyze variations of high-energy charged particle populations filling various magnetospheric regions under, inside, and outside of the Van Allen inner and outer electron radiat…
Solar Flare Composition and Thermodynamics from RESIK X-ray Spectra
B. Sylwester, J. Sylwester, K. J. H. Phillips +2
Previous estimates of the solar flare abundances of Si, S, Cl, Ar, and K from the RESIK X-ray crystal spectrometer on board the CORONAS-F spacecraft were made on the assumption of…
The SECIS instrument on the Lomnicky Peak Observatory
J. Ambroz, K. Radziszewski, P. Rudawy +2
Heating mechanisms of the solar corona will be investigated at the high-altitude solar observatory Lomnicky Peak of the Astronomical Institute of SAS (Slovakia) using its mid-size…
RESIK observations of He-like Ar X-ray line emission in solar flares
J. Sylwester, B. Sylwester, K. J. H. Phillips
The Ar XVII X-ray line group principally due to transitions 1s2 - 1s2l (l=s, p) near 4 Anstroms was observed in numerous flares by the RESIK bent crystal spectrometer aboard CORONA…
