Disentangling the stellar atmosphere and the focused wind in different accretion states of Cygnus X-1
M. Brigitte, P. Hadrava, B. Kubátová +8
In high-mass X-ray binaries (HMXBs), the compact object accretes the strong stellar wind of an O-B supergiant companion star. X-ray flux variations alter the stellar wind's ionizat…
