Super star clusters in the Blue Dwarf Galaxy UM 462

Vanzi L.

Abstract

I present optical observations of the Blue Compact Dwarf Galaxy UM 462. The images of this galaxy show several bright compact sources. A careful study of these sources has revealed their nature of young Super Star Clusters. The ages determined from the analysis of the stellar continuum and Ha are between few and few tens Myr. The total star formation taking place into the clusters is about 0.05 M?/yr. The clusters seem to be located at the edges of two large round-like structures, possibly shells originated in a previous episode of star formation. The sizes of the shells compare well with the ages of the clusters. Evidence for the presence of an evolved underlying stellar population is found.
