On Stellar Rotation: II. The Rotation of Lower Main Sequence Stars

Abstract

The first-order perturbation analysis developed in Paper I is extended to stars with a radiative core and convective envelope and with the proton-proton chain as the source of energy. The variation of angular velocity with distance from the centre of the star is calculated for a model of the Sun in its initial main-sequence state. The inward increase in angular velocity is too small to alter signifiantly the value of the star's angular momentum computed under the assumption of uniform rotation.
