A Quantitative Comparison of Opacities Calculated Using the Distorted- Wave and -Matrix Methods
F. Delahaye, N. R. Badnell, C. P. Ballance +7
The present debate on the reliability of astrophysical opacities has reached a new climax with the recent measurements of Fe opacities on the Z-machine at the Sandia National Labor…
Ultraviolet emission lines of Si II in cool star and solar spectra
Sibasish Laha, Francis P. Keenan, Gary J. ferland +6
Recent atomic physics calculations for Si II are employed within the Cloudy modelling code to analyse Hubble Space Telescope (HST) STIS ultraviolet spectra of three cool stars, Bet…
Electron-Impact Excitation Collision Strengths and Theoretical Line Intensities for Fine-Structure Transitions in S III
M. F. R. Grieve, C. A. Ramsbottom, C. E. Hudson +1
We present Maxwellian-averaged effective collision strengths for the electron-impact excitation of S III over a wide range of electron temperatures of astrophysical importance, log…
