| Abstract | A color-magnitude diagram for the dwarf galaxy Andromeda II (And II) is presented, based on CCD photometry obtained using the Palomar 5 m telescope and Thuan-Gunn g, r filters. The mean metallicity, the metallicity spread, and the distance to And II are estimated. The mean metallicity of the galaxy is found to be <[Fe/H]> = - 1.59_-0.12_^+0.44^, derived by superimposing globular cluster giant branches. This metallicity is consistent with the accepted M_V_ vs Fe/H] relationship for dwarf spheroidals. The spread in metallicity seems to be large, σ ~0.43, but we cannot determine the exact value. Andromeda II is estimated to be at a distance of 583_-103_^+124^ Kpc, ~120 Kpc closer than M31. |
