Scientific paper

We present a scenario in an attempt to account for the observed behavior of the periodic radiostar LSI+61 303 in different wavelength domains, from radio to X-rays. Our interpretation is based on modelling our previous observations of the LSI+61 303 near infrared light curve, which allows us to estimate the orbital eccentricity and phase of periastron passage. This information, together with the circumstellar envelope parameters derived from the observed infrared excess, is used in order to study the occurrence of supercritical accretion events leading to periodic radio outbursts. A possible interpretation of the 4yr modulation of the radio outburst peak is also proposed.
