Abstract

We present results to be soon published about NGC 288, which is a diffuse Galactic globular cluster, with the peculiarity of having internal accelerations below the critical MoND a0 acceleration throughout. This makes it an ideal candidate to test an analytic solution for the MoNDian brightness profile in isothermal spherical equilibrium, accounting for anisotropy (β) in the dispersion of velocities. By comparing and adjusting with observational data, we find, using the MoNDian model, that the cluster's kinematics fit best to a perfectly isotropic (β= 0) solution with a total mass of 3.5±1.1× 104M. We also compare our data with newtonian solutions, such as a Plummer profile, finding a slightly better approximation with our model.
