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…
The Solar Line Emission Dopplerometer project
J. -M. Malherbe, P. Mein, F. Sayede +4
Observations of the dynamics of solar coronal structures are necessary to investigate space weather phenomena and global heating of the corona. The profiles of high temperature lin…
Four decades of advances from MSDP to S4I and SLED imaging spectrometers
P. Mein, J. -M. Malherbe, F. Sayede +3
The Multichannel Subtractive Double Pass (MSDP) is an imaging spectroscopy technique, which allows observations of spectral line profiles over a 2D field of view with high spatial…
A Unique Resource for Solar Flare Diagnostic Studies: the SMM Bent Crystal Spectrometer
J. Sylwester, B. Sylwester, K. J. H. Phillips +2
The Bent Crystal Spectrometer (BCS) on the NASA Solar Maximum Mission spacecraft observed the X-ray spectra of numerous solar flares during the periods 1980 February to November an…
Analysis of Quiescent Corona X-ray Spectra from SphinX during the 2009 Solar Minimum
B. Sylwester, J. Sylwester, M. Siarkowski +3
The SphinX X-ray spectrophotometer on the {\em CORONAS-PHOTON}\/ mission observed the 1~--~15\,keV X-ray spectrum of the spatially integrated solar corona during the deep minimum o…
