Query: Tidal tails around globular clusters: are they good tracers of cluster
  orbits?   In the last decade, observational studies have shown the existence of tidal
streams in the outer part of many galactic globular clusters. The most striking
examples of clusters with well defined tidal tails are represented by Palomar 5
and NGC 5466 (both observed in the framework of the Sloan Digital Sky Survey),
which show structures elongated for 4 kpc and 1 kpc in length, respectively.
Unfortunately, most of the observational studies about globular clusters (GCs)
do not cover such a large field of the sky as the SDSS does. In this framework,
by mean of a parallel, adaptive tree-code, we performed detailed N-body
simulations of GCs moving in a realistic three-components (bulge, disk and
halo) Milky Way potential, in order to clarify whether and to what extent tails
in the clusters outer regions (few tidal radii) are tracers of the local orbits
and, also, if some kind of correlation exists among the cluster orbital phase
and the orientation of such streams.
