J/MNRAS/375/1381    Kinematics of RR Lyr and HB stars in NGP     (Kinman+, 2007)

Kinematic structure in the Galactic halo at the North Galactic Pole: RR Lyrae and blue horizontal branch stars show different kinematics. Kinman T.D., Cacciari C., Bragaglia A., Buzzoni A., Spagna A. <Mon. Not. R. Astron. Soc., 375, 1381-1398 (2007)> =2007MNRAS.375.1381K
ADC_Keywords: Galactic pole, north ; Stars, variable ; Space velocities ; Proper motions Keywords: stars: horizontal branch - stars: kinematics - stars: variables: others - Galaxy: halo - Galaxy: structure Abstract: Radial velocities and proper motions (derived from the GSC-II data base) are given for 38 RR Lyrae (RRL) stars and 79 blue horizontal branch (BHB) stars in a ∼200deg2 area around the North Galactic Pole (NGP). Both heliocentric (UVW) and galactocentric (VR, Vphi, Vz) space motions are derived for these stars using a homogeneous distance scale consistent with (m-M)0=18.52 for the Large Magellanic Cloud (LMC).
