4.12-Consider a particle of dust orbiting a star in a circular orbit, with velocity v. This particle absorbs stellar photons, heats up, and then emits the excess energy isotropically in its rest frame. a. Show that in absorbing a photon the angular momentum of the particle about the star does not change. (Assume the photons are traveling radially outward from the star.)
