- W2042221622 abstract "Radial velocities of small samples of G and K giants previously identified in high-galactic-latitude fields in SA 94 and Serpens are presented and analyzed for dependences on metallicity and galactocentric distances. In each field, the small samples of seven metal-poor stars with Fe/H less than -0.8 show mean radial velocities and high velocity dispersions expected for the halo population. For stars more metal rich than Fe/H = -0.8, there is no strong evidence in either field for a dependence of velocity dispersion on metallicity. In Serpens, the dispersion of 50 km/s for the 32 metal-rich stars is in good agreement with that expected for a thick-disk population. In SA 94, thirteen stars with Fe/H greater than -0.8 show a uniform dispersion of 29 km/s, in agreement with the expected old-disk kinematics. The contrast between results for the two fields is suggestive, but the small sizes of the samples prevent any strong conclusions from being drawn. 37 references." @default.
