Abstract (from CDS):

We present the first spectroscopic analysis of the faint and compact stellar system Draco II (Dra II, MV=-2.9±0.8, ), recently discovered in the Panoramic Survey Telescope and Rapid Response System 1 3π survey. The observations, conducted with DEIMOS on the Keck II telescope, establish some of its basic characteristics: the velocity data reveal a narrow peak with nine member stars at a systemic heliocentric velocity , thereby confirming Dra II is a satellite of the Milky Way; we infer a velocity dispersion with σvr=2.9±2.1 km/s ( and , in Solar units; furthermore, very weak calcium triplet lines in the spectra of the high signal-to-noise member stars imply [Fe/H]
