摘要
We present a study of star clusters in the interacting galaxy M51 using a star cluster catalog that includes about 3600 star clusters with m(F555W) < 23 mag, compiled by Hwang & Lee (2008). Combined with m(F336W)-band imaging data taken with the Hubble Space Telescope (HST)'s WFPC2 camera, we have derived the ages and masses of star clusters in M51 using theoretical population synthesis models. The cluster age distribution displays multiple peaks that correspond to the epochs of dynamical encounters predicted by theoretical model studies and the cluster-formation rate appears to increase around the same epochs.
