In this spirit we study the angular momentum transfer from a random background of radiation either to a rotating star or to an oscillating one. The angular momentum transferred to such objects by a continuous plane wave is proportional to time, $t$, and by an stochastic background is proportional to $t^{1/2}$.5 Pages, Presented in GR15Astrophysicstext
