Abstract

The galactic orbits of 10 globular and 3 galactic clusters have been obtained by direct numerical integration of the equations of motion; the model galactic potential that was used gives a good representation of the observed rotation curve in the region 1 - 15 kpc and a flat rotation curve out to 100 kpc. With the pericentric distances resulting from the computed orbits, cluster tidal radii have been obtained. The sensitivity of the results to errors in the observed cluster data and to model uncertainties is briefly discussed, and some implications for the fate of the globular cluster population of the Galaxy are pointed out.
