Catching Up on State Transitions in Cygnus X-1
Moritz Boeck, Manfred Hanke, Joern Wilms +6
In 2005 February we observed Cygnus X-1 over a period of 10 days quasi-continuously with the Rossi X-ray Timing Explorer and the Ryle telescope. We present the results of the spect…
Multi-Satellite Observations of Cygnus X-1 to Study the Focused Wind and Absorption Dips
Manfred Hanke, Joern Wilms, Moritz Boeck +4
High-mass X-ray binary systems are powered by the stellar wind of their donor stars. The X-ray state of Cygnus X-1 is correlated with the properties of the wind which defines the e…
Chandra X-ray spectroscopy of the focused wind in the Cygnus X-1 system. I. The non-dip spectrum in the low/hard state
Manfred Hanke, Joern Wilms, Michael A. Nowak +3
We present analyses of a 50 ks observation of the supergiant X-ray binary system Cygnus X-1/HDE 226868 taken with the Chandra High Energy Transmission Grating Spectrometer (HETGS).…
