标题： Dynamical Evolution of Globular Clusters in the Magellanic Clouds and Other Local Systems

摘要： 对富丽马Henize天文学集群和斯麦集群的观测显示，核心半径随年龄增加而增大。 这一趋势很可能代表了这些系统中真实的物理演化。 古老的麦哲伦云集群要么显得扩展，要么显得紧凑。 类似的核心半径分布也被观察到存在于仙女座和射手矮星系集群系统以及“年轻”的银河晕子系统中。 这些观测结果对银河系的形成和球状星团的动力学演化都有重要意义。 显示英文摘要

摘要： Observations of rich LMC and SMC clusters reveal an increasing spread in core radius with age. This trend likely represents real physical evolution in these systems. Old Magellanic Cloud clusters appear either extended or compact. Similar core radius distributions are observed for the Fornax and Sagittarius dSph cluster systems and in the ``young'' halo Milky Way subsystem. These observations have implications for both the formation of the Galaxy and the dynamical evolution of globular clusters.
