14 Sep 2001 | | Subject: | astro-ph | | Affiliation: | SNU), Doug Geisler (Concepcion), Ata Sarajedini(UFlorida), Taft E. Armandroff(NOAO), and Gary S. Da Costa(ANU | | Abstract: | We present the surface photometry of star clusters in the nearby dwarf elliptical galaxies NGC 185 and NGC 205, obtained from deep HST WFPC2 F555W (V) and F814W (I) images. We have obtained surface brightness and color profiles of six star clusters in NGC 185, seven star clusters in NGC 205, and one recently discovered non-stellar object in NGC 205. The surface brightness profiles of ten star clusters are fitted well by the King model, and those of four star clusters are fitted well by the power-law. Three out of ten star clusters fitted well with King model show signs of tidal tails. | | Source: | arXiv, astro-ph/0109218 | | Services: | Forum | Review | PDF | Favorites | |
