Evidence for the importance of resonance scattering in X-ray emission line profiles of the O star Puppis
Maurice A. Leutenegger, Stanley P. Owocki, Steven M. Kahn +1
We fit the Doppler profiles of the He-like triplet complexes of \ion{O}{7} and \ion{N}{6} in the X-ray spectrum of the O star Puppis, using XMM-Newton RGS data collected over $…
X-ray Spectral Study of the Photoionized Stellar Wind in Vela~X-1
Shin Watanabe, Masao Sako, Manabu Ishida +6
We present results from quantitative modeling and spectral analysis of the high mass X-ray binary Vela X-1 obtained with the Chandra HETGS. The spectra exhibit emission lines from…
Capella Corona Revisited: A Combined View from \textit{XMM-Newton} RGS, \textit{Chandra} HETGS, and LETGS
M. F. Gu, R. Gupta, J. R. Peterson +2
We present a combined analysis of the X-ray emission of the Capella corona obtained with \textit{XMM-Newton} RGS, \textit{Chandra} HETGS, and LETGS. An improved atomic line databas…
On the Putative Detection of z>0 X-ray Absorption Features in the Spectrum of Markarian 421
Andrew P. Rasmussen, Steven M. Kahn, Frits Paerels +3
In a series of papers, Nicastro et al. have reported the detection of z>0 OVII absorption features in the spectrum of Mrk421 obtained with the Chandra Low Energy Transmission Grati…
