Unformatted text preview: e galaxy (in solar masses). Compare your answer with the value quoted in the Figure 25.37 The stellar velocity dispersion and rotational velocities of stars near the center of M31. measured along the major axis of the bulge. Given the distance to Andromeda of 770 kpc, 1" corresponds to a linear distance from the center of 3.7 pc. (Data from Bender et al., Ap. J., 631, 280. 2005.) – Page 1 of 3 – text (on page 959). b. Estimate the amount of mass within the central 1" based on the velocity dispersion data. HINT: Use the peak velocity dispersion and assume by the phrasing the question the black...
