Wide Field Observations of the Ursa Minor dSph galaxy
D. Martinez-Delgado, A. Aparicio
Abstract
Ursa Minor (UMi) is one of the closest satellites of the Milky Way (d=69 kpc). It is possibly a disrupted dSph interacting with the external Galactic halo. This makes its study quite necessary in the forementioned context. In this paper we present preliminary results of a wide field photometry survey of UMi and discuss the presence of an intermediate-age population and tidal tails in it.
