Stars formed out of an interstellar cloud contain a certain amount of angular momentum, which is distributed over the stellar mass. Suppose there were no transport of angular momentum between the mass elements during the formation and evolution of the stars; one would then have local conservation of angular momentum. Then the angular velocity would be determined by the angular momenta of the mass elements in the original cloud. However, the motion of atoms, the flow of photons through matter, and instabilities that cause small-scale motions can transport angular momentum. We now discuss these transport mechanisms in detail.
