    Abstract:

    We present an investigation of the halo dynamics of M31 using planetary nebulae (PNe) velocities. We describe our current velocity data, and imaging to enable spectroscopy to be performed deeper into the galaxy halo (~ 20 kpc). In the future we will measure the total mass, mass distribution and velocity anisotropy as a function of radius. We plan to compare kinematics of the globular cluster and PNe populations to test if both trace similar stellar populations.
