ABSTRACT

We present the results of a detailed UV-optical study of some of the stellar clusters in the nearby dwarf starburst galaxy NGC 4214 using multifilter HST/WFPC2+STIS photometry. The data show the existence of both young and old stellar populations that can be resolved at the distance of NGC 4214 (2.94 Mpc). We detected a number of massive clusters and associations with ages between a few and 200 million years and we derived their physical properties by comparing our photometry with low metallicity starburst99 cluster models.
