Abstract
We show that X-ray illumination by the central source intensifies the viscously driven mass loss from the surface of an accretion disc. The optical depth of the wind, and its constancy with central accretion rate, are in good agreement with observations of accretion disc corona (ADC) sources in low-mass X-ray binaries. We show that more than half of the mass transfer rate may be blown away from the disc for typical binary parameters, in contrast to earlier work which suggested such an effect only for long orbital periods (≳ 15 hr).Keywords
