Abstract

We analyze the stellar population parameters of seven ultra-compact dwarfs (UCDs) in the Virgo cluster. We find that the stellar population properties of UCDs are similar to those nuclei of early-type dwarf galaxies (dEs) that lie in the dense region of the cluster. This evidence suggests that the Virgo UCDs may have formed through the stripping of dE nuclei.
