The Phoenix Dwarf is a

Phoenix constellation
.

Characteristics

The Phoenix Dwarf has an inner part of young stars which is stretched in an east-west direction and an outer part of mainly old stars that is stretched north-south. The central region's rate of star formation seems to have been relatively constant across time (Martínez-Delgado et al. 1999). In 1999, St-Germain et al. discovered a H I region of about 105 M☉ just to the west of Phoenix. Its radial velocity is −23 km/s and may be physically associated with Phoenix if it is found to have a similar radial velocity.[7]
