Radial velocites of RR Lyrae stars in the Baade Window.
Abstract
Radial velocities for 17 RR Lyrae stars in the Baade Window are presented. Once reduced for the solar motion, the systemic velocity of +11±34 km s-1 is obtained, with a single star dispersion of 133±25 km s-1. These values agree with systemic velocities and dispersions obtained from other components of the galactic bulge.
