Abstract
A comparison between the stellar-wind interaction model with electron heat conduction and the ASCA X-ray observations of the (WR+O) binary system WR 140 has been made for the first time. This comparison shows that good agreement with observations can be achieved by varying the physical stellar-wind parameters within the ranges allowed by the accuracy of their determination. The self-consistent two-temperature model with heat conduction is an outgrowth of the model of interacting winds in such systems, which is required to properly interpret future detailed X-ray observations on the Chandra and Newton-XMM satellites.
