1999ApJ...515L..17C Objects in NGC 205 Resolved into Stellar Associations by Hubble Space Telescope Ultraviolet Imaging MICHELE CAPPELLARI, FRANCESCO BERTOLA, DAVID BURSTEIN, LUCIO M. BUSON, LAURA GREGGIO, AND ALVIO RENZINI Received 1999 January 7; accepted 1999 February 5; published 1999 February 22 ABSTRACT We have obtained high-resolution UV images with the Hubble Space Telescope/Wide-Field Planetary Camera 2 of the central region of the dwarf elliptical galaxy NGC 205. Our images reveal that many of the hot UV stars previously detected and studied from the ground are actually multiple systems, open clusters, and star associations. We have performed photometry of two such clusters, and we find that our data are consistent with stellar ages of 50 and 100 Myr, respectively. From the number of massive stars in NGC 205, we estimate that the star formation episode in this galaxy has turned ~1000 M_sun_ of gas into stars over the last 100 Myr. Subject headings: galaxies: individual (NGC 205)-galaxies: star clusters
