Dynamical evolution of M92 globular cluster

N-body numerical simulations are used to study the dynamical evolution of the globular cluster M92 in the Galaxy gravitational field during the last Gyr, which corresponds to aproximately 8 perigalactic transits. The cluster was modelled with 128K particles covering a mass spectrum from 0.1-1.2 M-circle dot. During the simulation we observe the appearance of several hundreds of parsecs of long tidal tails, which tend to align with the cluster orbit. The model reproduces quite well the observed density profile and surface density map recently obtained by Testa et al. (2000), including the isodensities orientation.
