Abstract

The projected mass method of Bahcall and Tremaine has been used to derive the mass of the core of M31. From the observed radial velocities of 43 globular clusters, the mass interior to 30' is found to be MI = (9 ± 2) × 1010 Msun. For six clusters with 100' MI = (2.4 ± 1.2) × 1011 Msun. From the observed radial velocities of M32, M33, NGC 147, NGC 185, NGC 205, and LGS 3, the total mass of the Andromeda Subgroup of the Local Group is calculated to be MI = (7.5 ± 3.9) × 1011 9) Msun.
