Scientific paper

The tidal interaction of globular clusters with the Galactic bulge is studied. We employ a Galactic potential that includes a bar. In particular, clusters with orbits residing in the bar region are considered. We calculate the tidal force on the real orbit of globular clusters, rather than the usual straight-line approximation. With ideas developed by Gnedin et al. (1999), we estimate the adiabatic correction for the internal heating of globular clusters using a fit for the tidal force. The tidal force in a barred potential behaves in a more complex way than in an axysimmetric potential.
