Effects of Wind-Wind Collision in Close Binary Stars

Various observational appearences of the effects of wind-wind collision for binary stellar systems have been discovered recently in X-ray, UV, optical, IR and radio ranges. Recent 3D gas-dynamic simulations of the wind-wind collision regions in WR+O, O+O and symbiotic binary systems allow to understand the physics of wind-wind collision effects, provide interpretation of observational data and constrain basic parameters of winds as well as those of binary systems. This revised version was published online in July 2006 with corrections to the Cover Date.
