dc.descriptionThe High Mass X-ray Binaries (HMXRB's) SMC X-1 and 4U1700-37 have been observed with FUSE to study the effect of the X-ray source on the stellar wind of the primary. In both systems phase dependent changes in the wind lines have been observed, indicating the creation of a X-ray ionization zone in the stellar wind. The high X-ray luminosity of SMC X-1 ionizes much of the wind and leaves a Stromgren zone. This disrupts the resonance-line acceleration of the wind in portions of the orbit, quencing the wind and disrupting the mass flow. A similar but less dramatic effect was found for the first time in 4U1700-37. This so-called Hatchett-McCray (HM) effect had been predicted for 4U1700-37, but was not previously detected.
