Query: Star Cluster Evolution with Primordial Binaries   Observations and theoretical work suggest that globular clusters may be born
with initially very large binary fractions. We present first results from our
newly modified Monte-Carlo cluster evolution code, which treats binary
interactions exactly via direct N-body integration. It is shown that binary
scattering interactions generate significantly less energy than predicted by
the recipes that have been used in the past to model them in approximate
cluster evolution methods. The new result that the cores of globular clusters
in the long-lived binary-burning phase are smaller than previously predicted
weakens the agreement with observations, thus implying that more than simply
stellar dynamics is at work in shaping the globular clusters we observe today.
