On the pre-RLO spin-orbit couplings in LMXBs
Abstract
We investigate the effect of orbital decay caused by nuclear expansion of a (sub)giant star in synchronous binary system. We compare this effect with the presence of a magnetic stellar wind and show that the additional transfer of orbital angular momentum into spin angular momentum is relatively important -- especially since it has been shown that the effect of magnetic braking saturates at short orbital periods.
