Spins of stripped B stars support magnetic internal angular momentum transport
Abstract
The galactic binary star LB-1 contains a recently stripped B-type star. Comparing its properties to detailed binary star models shows that tidal braking and magnetic torques lead to low surface rotational velocities in the stripped donors after Roche-lobe over)ow. Models without magnetic torques cannot reproduce the observed low surface rotation.
