Abstract
Recently we proposed that gas funnelled by magnetic field lines from a n accretion disc on to a magnetized compact star does not exert a sign ificant material torque on the star. We show that a consequence of thi s result is that in rotational equilibrium the true inner disc radius is significantly smaller than the corotation radius (<(omega)over bar> (in)/<(omega)over bar>(co) similar or equal to 0.10-0.74).
