Unformatted text preview: urbed inward, orbit at an angular velocity faster than that of the “guiding center?” HINT: The forces mentioned in (a) are radial, why is this critical? c. Why would a star, in the rotating frame, if perturbed outward from this “guiding center,” experience a restoring force pulling it back toward smaller orbits? Inversely, when the star is perturbed inward from the “guiding center,” why does it experience a restoring force pushing it back outward toward larger orbits? d. Explain how the effects described in (b) and (c) explain why we would expect stars perturbed from perfectly circular orbits to exhibit ep...
