The Be/X-ray Binary LSI+61303 in terms of Ejector-Propeller Model

We tested the ejector-propeller model of the Be/X-ray binary LSI+61303 (V 615 Cas, GT 0236+620) by using the parameters predicted by the model in the calculations of the X-ray and radio variability. The results are: (1) in terms of the Ejector-Propeller model, the X-ray maximum is due to the periastron passage; (2) the radio outburst can be really a result of the transition from the propeller to ejector regimes; (3) the radio outburst will delay with respect to the X-ray maximum every orbital period. The proposed scenario seems to be in good agreement with the observations.
