The Phoenix dwarf has an inner part of young stars running in an east-west direction and an outer part of mainly old stars that runs north-south. The central region's rate of ] seems to have been relatively constant across time (Martínez-Delgado et al. 1999). In 1999, St-Germain et al. discovered a ] region of about 10<sup>5</sup> ] just to the west of Phoenix. Its ] is -23 km/s and may be physically associated with Phoenix if it is found to have a similar radial velocity.<ref name="Bergh2000">{{ Cite journal |
