Finding cool subdwarfs using a V-J reduced proper-motion diagram: stellar parameters for 91 candidates.

YONG D. and LAMBERT D.L.

Abstract (from CDS):

We present the results of a search for cool subdwarfs for which our candidates were drawn from a V-J reduced proper-motion diagram constructed by Salim & Gould. Kinematic (U, V, and W) and self-consistent stellar parameters (Teff, logg, [Fe/H], and ξt) are derived for 91 candidate subdwarfs based on high-resolution spectra. The observed stars span 3900 K<Teff< 6200 K and -2.63<[Fe/H]<0.25 including only three giants (logg<4.0). Of the sample, 77 stars have MgH lines present in their spectra. With more than 56% of our candidate subdwarfs having [Fe/H]≤-1.5, we show that the V-J reduced proper-motion diagram readily identifies metal-poor stars.
