Abstract

The theory of magnetic braking by a thermo-centrifugal stellar wind is summarized. The basic result — ‘effective corotation’ out to the Alfvén surface — yields approximate laws for the spin-down of late-type stars, if one adopts a simple phenomenological dynamo relation between magnetic flux and angular velocity, and a similar relation between mass loss and magnetic flux. Comparison with the observed distributions of angular velocity in young stellar clusters already sets stringent constraints on the theory.
