Phoenix Dwarf : ウィキペディア英語版 | Phoenix Dwarf
The Phoenix Dwarf is a dwarf irregular galaxy discovered in 1976 by Hans-Emil Schuster and Richard Martin West and mistaken for a globular cluster. It is currently 1.44 Mly away from Earth. Its name comes from the fact that it is part of the 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 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.
