X ray emission line profile modeling of hot stars
Roban H. Kramer, Stephanie K. Tonnesen, David H. Cohen +3
The launch of high-spectral-resolution x-ray telescopes (Chandra, XMM) has provided a host of new spectral line diagnostics for the astrophysics community. In this paper we discuss…
X-ray Emission Line Profile Modeling of O stars: Fitting a Spherically-Symmetric Analytic Wind-Shock Model to the Chandra Spectrum of zeta Puppis
Roban H. Kramer, David H. Cohen, Stanley P. Owocki
X-ray emission line profiles provide the most direct insight into the dynamics and spatial distribution of the hot, X-ray-emitting plasma above the surfaces of OB stars. The O supe…
High-Resolution {\it Chandra} Spectroscopy of tau Scorpii: A Narrow-Line X-ray Spectrum From a Hot Star
David H. Cohen, Geneviève E. de Messières, Joseph J. MacFarlane +4
Long known to be an unusual early-type star by virtue of its hard and strong X-ray emission, tau Scorpii poses a severe challenge to the standard picture of O-star wind-shock X-ray…
