The interaction of two stellar winds in a binary system containing a late supergiant and an early main sequence star is analyzed for the limited case where the orbital velocity is assumed to be negligible relative to wind velocity and the shock front is assumed to be negligibly thin compared with the separation of the stars. Under these assumptions, the condition of stationarity gives a system of differential equations which describes the front and which is solved numerically. The geometrical structure is shown to depend only on one parameter for all systems and numerical results are presented for a wide range of parameter values. The results are tentatively applied to the binary system Alpha Scorpii, where some observed features can indeed easily be explained.
