It is known that a magnetically channelled wind from the secondary star in a close binary, together with tidal coupling, leads to a continuous loss of orbital angular momentum. The consequent shrinkage of the secondary's Roche lobe drives mass transfer, via overflow through the L1 region. Expressions are derived here for the mass transfer rate, using fast rotator braking theory, for a variety of d...
