Scientific paper

Data analysis results for the 1969-79 all-sky coverage of the hard spectrum, pulsating X-ray transient A0535+26 obtained by the scintillator-photomultiplier on the Vela 5B spacecraft are presented. Fourier analysis of the time history demonstrates the existence of the 111-day period suggested by Nagase et al. (1982). The giant outbursts in April 1975 and September 1980 appear out of phase with the period, suggesting an origin different from the smaller events. The May 1975 to June 1979 mean luminosity is consistent with the secular spinup observed by Nagase. Calculation of the wind mass flux required to feed the X-ray source shows that it exceeds the expected value by a factor of over 1000. It is more likely that the transferred matter is lost from the equatorial region of the rapidly rotating B star.
