Laboratory Calibrations of Fe XII-XIV Line-Intensity Ratios for Electron Density Diagnostics
Thusitha P. Arthanayaka, Peter Beiersdorfer, Gregory V. Brown +5
We have used an electron beam ion trap to measure electron-density-diagnostic line-intensity ratios for extreme ultraviolet lines from F XII, XIII, and XIV at wavelengths of 185-20…
Chandra X-ray spectroscopy of the focused wind in the Cygnus X-1 system III. Dipping in the low/hard state
Maria Hirsch, Natalie Hell, Victoria Grinberg +9
We present an analysis of three Chandra High Energy Transmission Gratings observations of the black hole binary Cyg X-1/HDE 226868 at different orbital phases. The stellar wind tha…
Chandra X-Ray Spectroscopy of the Focused Wind in the Cygnus X-1 System. II. The Nondip Spectrum in the Low/Hard State - Modulations with Orbital Phase
Ivica Miškovičová, Natalie Hell, Manfred Hanke +14
The accretion onto the black hole in the system HDE 226868/Cygnus X-1 is powered by the strong line driven stellar wind of the O-type donor star. We study the X-ray properties of t…
