Scientific paper

Arguments showing that the forced precession of the rotation axis of the optical star in an X-ray binary, and the accompanying long-period optical and X-ray variability may be common to all X-ray binaries, are presented. Variability periods range from 30.5 days to 165 days, and the ratio of this period to the orbital period does not differ much for the different systems. Estimations of forced precession periods agree with long-term variability observations, implying that X-ray binaries are a result of supernova explosions in the system. This suggests that the rotation axis of the optical star is undergoing forced precession, if the axis is oblique to the orbit plane of the binary system. Having concluded that a less massive component of the binary explodes the supernova, an eccentric orbit and long-term variability should be the effects, but as systems differ in the amplitude and direction of the asymmetry of their supernova outburst, observable evidence of these effects may not exist.
