GT HD 93403 is an eccentric (e0.52) spectroscopic binary of spectral typeO5(f) + O7III with an orbital period of 15.09 days situated within the HIIregion around Eta Carinae. From the Xray light curve of a colliding windsbinary system we can constrain the mass loss rates of the two stars andinvestigate the hydrodynamical properties of their winds.
