Unformatted text preview: icyclic motion in a rotating frame rotating at the angular velocity of the perfectly circular orbit. 5. Explain, in English, why if the epicyclic frequency of a star is equal to some integer multiple of the frequency at which it encounters spiral arms, the star – Page 2 of 3 – would experience “resonant forcing”? 6. [C&O 25.14 (extensively tweaked)] In example 25.3.1 in the textbook, Carroll and Ostlie work out the epicyclic frequency of the Sun, κ0. Using that information along with what we know about the Sun’s velocity relative to the LSR (velocity components given in equations 24.33 to 24.35), work out the amplitude AR of the Sun’s radial...
