Abstract

The Phoenix dwarf galaxy is the nearest and most typical representative of the class of the so-called transition dwarf galaxies (from spheroidal to irregular). We present here precise velocity measurements obtained from high-resolution spectroscopy of more than one hundred member stars, allowing us to study the stellar kinematics and estimate the internal velocity dispersion and dark matter content.
