In case of moderate matter mixing in the semi-convective zone the primary loses part of its mass on a nuclear time-scale. It looks like a CNO-supergiant during the first part of the helium burning stage. Another part of the mass is lost on the thermal time-scale. The primary looks like a WR star during the second part of the helium burning stage.
