The Be star LSI +61
303 shows the 1584 d period in its X-ray
emission. The difference in the 1584 d period phases of the peak X-ray
and radio emissions and the Hα emission is explained as
being due to the time
taken by the density enhancement, emitted by the Be star, and which is
responsible for the increased emissions, to reach the periastron of the orbit
of the binary companion.
