Query: Destruction of the Galactic Globular Cluster System   We investigate the dynamical evolution of the Galactic Globular Cluster
System in considerably greater detail than has been done hitherto, finding that
destruction rates are significantly larger than given by previous estimates.
More than half of the present clusters (52%-58% for the OC galactic model, and
75%-86% for the BSS model) will be destroyed in the next Hubble time. For the
evolution of individual clusters we use a Fokker-Planck code including two-body
relaxation, tidal truncation of clusters, compressive gravitational shocks
while clusters pass through the Galactic disk, and tidal shocks due to passage
close to the bulge. Gravitational shocks are treated comprehensively, using a
recent result by Kundic & Ostriker (1995) that the shock-induced relaxation
term, driving an additional dispersion of energies, is generally more important
than the usual energy shift term. We discuss some implications for a past
history of the Globular Cluster System, and the initial distribution of the
destruction times raising the possibility that the current population is but a
very small fraction of the initial population with the remnants of the
destroyed clusters constituting presently a large fraction of the spheroid
(bulge+halo) stellar population.
