CDROM/AJ/V107/P2240 Proper Motion Stars (Carney+ 1994) ================================================================================ A Survey of Proper Motion Stars. XII. An Expanded Sample Bruce W. Carney, David W. Latham, John B. Laird, & Luis A. Aguilar <1994, AJ, 107, 2240> =1994AJ....107.2240C ================================================================================ Abstract: We report new photometry and radial velocities for almost 500 stars from the Lowell Proper Motion Catalog. We combine these results with our prior sample and rederive stellar temperatures based on the photometry, reddening, metallicities (using Chi^2 matching of our 22,500 low S/N high resolution echelle spectra with a grid of synthetic spectra), distances, space motions, and Galactic orbital parameters for 1269 (kinematics) and 1261 (metallicity) of the 1464 stars in the complete survey. The frequency of spectroscopic binaries for the metal-poor ([m/H] <= -1.2) stars with periods shorter than 3000 days is at least 15%. The spectroscopic binary frequency for metal-rich stars ([m/H] > -0.5) appears to be lower, about 9%, but this may be a selection effect. We also discuss special classes of stars, including treatment of the double-lined spectroscopic binaries, and identification of subgiants. Four possible new members of the class of field blue stragglers are noted. We point out the detection of three possible new white dwarfs, six broad-lined (binary) systems, and discuss briefly the three already known nitrogen-rich halo dwarfs. The primary result of this paper, Table 6, will be available on CD-ROM, in the form of a much larger table from which it was drawn.
