Abstract
It is sometimes suggested that the change from the horizontal to the n ormal branch in the X-ray intensity-hardness ratio diagram of low mass X-ray binaries, is due to a change from a thin to a thick disk. It is shown here that wind from the hot thick disk depletes the amount of m atter reaching the neutron star, thus causing the observed reduction o f X-ray intensity as hardness ratio decreases in the normal branch.
