UGC 7639: A Dwarf Galaxy in the Canes Venatici I Cloud

Figure 2

(a) GALEX NUV and FUV and optical r- and g-band surface brightness profiles of UGC 7639 (magenta squares, cyan triangles, and red and green circles, resp.) versus circularized radius. (b) (FUV-NUV) color profile. (c) UV/optical (NUV-r) color profile. Since BCDs experience mostly off-centered star formation (cf. [18]), these profiles could be affected by the difficult identification of the main stellar body centre.
