Periodicities in the photometric variability of SS433.
Abstract
An analysis of periodicities in light variations of SS433 is carried out on the basis of observations covering the years 1978 - 1988. The character of regular photometric variability is investigated with the periods 162d.5, 13d.082 and 6d.286. The flare activity of SS433 is also analysed. The quasiperiod ≡26d in the variability of the shape of the primary minimum of the light curve is found.
