abstract:

Some of the Galactic "outer halo globular clusters" are excellent tools to probe gravitational theories in the regime of weak accelerations. The measurement of the line-of-sight velocity dispersion among stars in these clusters will differentiate between the validity of Newtonian dynamics (low velocity dispersion) and the possibility of modified Newtonian dynamics (MOND) or dark matter dominated globular clusters (high velocity dispersion). In this talk I will give a brief review of recent studies in this field. I will present a brief report on recently simulated cluster Pal 14 by Newtonian Nbody simulation code, Nbody6.
