Abstract.

An intriguing property of the star clusters in the Large Magellanic Cloud (LMC) is that the range of observed cluster core radii R c increases with the ages of the clusters. We use N-body simulations to study two possible dynamical mechanisms which could lead to variations in R c evolution between clusters. We demonstrate that neither large differences in primordial binary fraction nor a time-dependent tidal field can account for the observed trend. Finally, we discuss briefly the possibility that the trend in R c may be the imprint of variations in the environment of cluster formation.
