WR+O star binary systems produce a region of hot shocked plasma where the stellar winds collide - the wind-collision region (WCR). The hot plasma produces thermal X-ray emission, while synchrotron radio emission arises from relativistic electrons believed to be accelerated at the shocks bounding the WCR. Such systems provide an excellent laboratory for the study of shock thermalization and particle acceleration, with the same physical processes as observed in SNRs, but at much higher mass, photon, and magnetic energy densities. We propose an X-ray observation of WR146 to search for signs of weak shock heating and shock modification, and to determine the non-thermal particle distribution, providing insight into the nature of particle acceleration and its feedback on the shock structure.
