  • In X-ray binaries, gravitational energy is converted into X-rays through mass accretion by a black hole or neutron star. Those are used in this work to screen the environment of the compact object. The focus is on the Cyg X-1 / HDE 226868 system, of which numerous observations with various X-ray observatories have been analyzed in particular view of the absorption by the blue supergiant's stellar wind. The results give detailed insight into the wind structure and dynamics.
  • In Röntgendoppelsternen wird Gravitationsenergie durch Massenakkretion eines Schwarzen Lochs oder Neutronensterns in Röntgenstrahlung umgewandelt, die in dieser Arbeit verwendet wird, um die Umgebung des kompakten Objekts zu durchleuchten. Der Schwerpunkt liegt auf dem System Cyg X-1 / HDE 226868, von dem zahlreiche Beobachtungen mit verschiedenen Röntgenobservatorien spektroskopisch in besonderer Hinsicht auf die Absorption durch den Sternwind des blauen Überriesen untersucht wurden. Die Ergebnisse geben einen detaillierten Einblick in die Windstruktur und -dynamik.
