Probing the LHS catalog. II. Faint proper-motion stars.


Abstract (from CDS):

We present low-resolution spectroscopic observations of faint proper-motion stars from the LHS Catalogue, concentrating on stars with mr>16.5 and µ>0".5/yr. The present paper includes observations and spectral classifications for 294 M dwarfs, M subdwarfs (sdM), and extreme M subdwarfs (esdM). We also identify white dwarfs among the faintest LHS stars. We have cross-referenced this sample against the Two Micron All Sky Survey (2MASS) sources, and list data for the detected objects. We discuss stars of individual interest, as well as the characteristics of the overall sample. As expected, a significant number of the stars in this proper-motion-selected sample are halo subdwarfs, including an esdM dwarf, LHS 3481, that is likely to lie within 20 pc of the Sun. None of the subdwarfs show Hα emission.
