The “Draco tidal tails” issue concerns whether the Draco dwarf spheroidal galaxy shows extended stellar streams indicative of strong tidal stripping by the Milky Way, or instead remains a compact, dark-matter–dominated system with little evidence of disruption (Odenkirchen et al. 2001; Wilkinson et al. 2004). In ΛCDM, Draco’s high velocity dispersion and large inferred mass-to-light ratio are usually attributed to a massive dark halo, but if significant tidal tails exist they could mimic high dispersions without requiring so much dark matter, while the apparent lack of clear, long tidal features in deep imaging and kinematic studies constrains both Draco’s orbit and the allowed inner density profile of its halo, leaving a narrow and somewhat fine-tuned range of tidal histories consistent with the data (Klessen et al. 2003; Lokas et al. 2005).
