Scientific paper

We present an analysis of the Draco dwarf spheroidal galaxy based on data taken with the Wide Field Camera at the INT and and with the DEIMOS multi-object spectrograph on the Keck2. The new photometric data are deeper than the previous studies, and permit a tentative detection of symmetric tidal tails along the major axis of Draco. These results suggest that the dark matter halo around the dwarf spheroidal galaxy is not as massive as indicated by previous studies, and could be affected by the Milky Way tides.
