The supersonic winds of the most luminous stars carry kinetic energy as well as mass. Where such stars are members of binary systems, some of this energy is released in strong shocks which form on both sides of the wind-collision boundary. Originally, the consequent heating of the gas in such systems was predicted to make the stars strong X-ray sources. However, the most conspicuous colliding-wind effects have been observed at longer wavelengths: synchrotron radiation from the shock-accelerated electrons and, most unexpectedly, infrared emission from dust condensing in the shock-compressed gas. Recent developments in observational techniques, especially increased spatial resolution, have led to delineation of these effects, and extensive observing campaigns have given a better idea of their incidence.
