The detection of the Sc-44 nuclear de-excitation lines and hard X-ray emission from Cas A
Jacco Vink, J. Martin Laming
We discuss the detection of Sc-44 (product of Ti-44) in the supernova remnant Cas A with the BeppoSAX-PDS instrument, and elaborate on the nature of the hard X-ray continuum, which…

Uncertainties in Dielectronic Recombination Rate Coefficients: Effects on Solar and Stellar Upper Atmosphere Abundance Determinations
Daniel Wolf Savin, J. Martin Laming
We have investigated how the relative elemental abundances inferred from the solar upper atmosphere are affected by uncertainties in the dielectronic recombination (DR) rate coeffi…
