Abstract (from CDS):

We investigate and parameterize high proper motion red stars in the Torino Observatory Parallax Program. Observations of 27 objects were made over the period 1994-2001 on the 1.05m Torino telescope. The trigonometric parallaxes and proper motions were determined using standard techniques. We determine parallaxes and proper motions, and by comparison to models we infer masses, ages, and metallicities. Of the 27 objects, 22 are within 25pc and 4 appear to be subdwarfs. There are published parallaxes for 18 objects, and all but 4 agree to within 2σ. The discrepancies are discussed.
