We present X-ray spectral ts to a recently obtained Chandra grating spectrum of Carinae, one of the most massive and powerful stars in the Galaxy and which is strongly suspected to be a colliding wind binary system. Hydrodynamic models of colliding winds are used to generate synthetic X-ray spectra for a range of mass-loss rates and wind velocities. They are then tted against newly acquired Chandra grating data. We nd that due to the low velocity of the primary wind (500 km s 1 ), most of the…

The column density to the hardest emission component, N H ~1024 H cm-2, marked one of the highest values ever observed for η Car, strongly suggesting the increased obscuration of the wind-wind colliding X-ray emission by the thick primary stellar wind prior to superior conjunction.
X-Ray Spectral Variation of η Carinae through the 2003 X-Ray Minimum
