Quantitative analysis of resolved X-ray emission line profiles of O stars
David H. Cohen, Maurice A. Leutenegger, Richard H. D. Townsend
By quantitatively fitting simple emission line profile models that include both atomic opacity and porosity to the Chandra X-ray spectrum of Pup, we are able to explore the tra…

Resonance scattering in the X-ray emission line profiles of Zeta Puppis
M. A. Leutenegger, D. H. Cohen, S. M. Kahn +2
We present XMM-Newton Reflection Grating Spectrometer observations of pairs of X-ray emission line profiles from the O star Zeta Pup that originate from the same He-like ion. The t…
