A sample of early‐type dwarf galaxies of the Virgo cluster extracted from the Sloan Digital Sky Survey is analyzed to search for two different populations: galaxies which were formed in the cluster and galaxies which were accreted at a later stage and which were stripped during this process. Photometric and spectroscopic data has been used for the analysis. Due to the low signal‐to‐noise ratios of the data, the results are however inconclusive (© 2009 WILEY‐VCH Verlag GmbH & Co.
