Rotation curve and mass distribution in M31

Journal Article · · Mon. Notic. Roy. Astron. Soc., v. 165, no. 1, pp. 9P-13P
The existing evidence is reviewed, and new 21-cm H I data are presented, concerning the shape of the rotation curve both in the inner and the outer parts of M31. It is concluded that a substantially constant value for the mass-to- luminosity ratio as a function of radius both for the spheroidal and the exponential disk components of the distribution of luminosity is in good agreement with the observations.
