摘要

The age, mass, and size distributions of star clusters in nearby star-forming galaxies provide important clues to the formation and evolution of cluster systems. In particular, the similarities and differences between these cluster distributions in very different environments can help to disentangle formation and disruption processes. We present the age and mass distributions for clusters younger than ≈1 Gyr in the Magellanic Clouds, which are typical, star-forming irregular galaxies, and compare the results with the more “extreme” environment found in the merging Antennae galaxies. In addition, we describe some new results on the interpretation of ancient globular cluster systems, and present an emerging picture for the life cycle of star clusters.
