Abstract
Flow of matter onto strongly magnetized neutron stars in X-ray binarie s proceeds through accretion funnels that roughly follow geometry of t he magnetic field. X-rays originate near the surface of the neutron st ar, and it may happen that the accretion flow passes through the line of sight as the star rotates. We consider the effects of such accretio n flow eclipses on the X-ray light curves of accretion powered pulsars , and present a set of X-ray light curves measured by BATSE for A0535262 for which this phenomenon is very likely to take place.
