J/AJ/137/3198      New samples of BHB stars in the Milky Way    (Kinman+, 2009)

Do the nearby blue horizontal branch stars belong to the thick disk or the halo? Kinman T.D., Morrison H.L., Brown W.R. <Astron. J., 137, 3198-3209 (2009)> =2009AJ....137.3198K
ADC_Keywords: Stars, nearby ; Stars, horizontal branch ; Space velocities Keywords: Galaxy: halo - Galaxy: structure - stars: horizontal-branch Abstract: We study the Milky Way region (|Z|<3.0kpc) where the thick disk and inner halo overlap by using the kinematics of local blue horizontal branch (BHB) stars (within 1kpc) and new samples of BHB stars and A-type stars from the Century Survey. We derive Galactic U, V, and W velocities for these BHB and A-type star samples using proper motions from the NOMAD catalog. File Summary:
