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...
