Abstract

M82 B is a several 100 Myr old starburst site located in the eastern part of the M82 disc. Using evolutionary population synthesis models, we derive the distributions of ages and metallicities of the star clusters located in this fossil starburst site. Our analysis is based on the comparison of BVIJ photometry with the colours of single-generation stellar populations. We confirm the peak in the cluster formation rate detected by de Grijs et al. (2001) and show that M82 B went through a chemical enrichment phase up to super solar metallicities about 1 Gyr ago. At almost the same time, however, a subpopulation of metal-poor clusters formed in the part of M82 B nearest the galactic centre.
