Subdwarfs among the old disk population.
Abstract
The radial velocity has been determined for the subluminous M dwarf AC + 54C1646 - 56. The resulting space motion is relatively low, suggesting that the star is a member of the old disk population. We then show that this star, and others with old disk motions, are subluminous in the theoretical H-R diagram. Subject headings: stars: late type - stars: subdwarfs
