Cg. Tinney et al., TRIGONOMETRIC PARALLAXES AND THE HR DIAGRAM AT THE BOTTOM OF THE MAIN-SEQUENCE, The Astronomical journal, 110(6), 1995, pp. 3014-3034
The final results of a parallax program carried out with the 1.5 m tel
escope on Palomar Mountain are presented, Astrometry has been obtained
for 34 very low-mass (VLM) stars, one white dwarf, and a serendipitou
sly discovered proper motion star, Sixteen of these stars have new (or
improved) parallaxes and proper motions, and a further eighteen have
proper motions alone. Common proper motions have also been determined
for two VLM binary systems; GD 165AB and TVLM 513-42404AB. The latest
atmospheric and interior models for low-mass stars are combined to pro
duce isochrones in the observational M(K): I-K plane, Remarkable agree
ment is seen between both the solar metallicity and low metallicity mo
dels, and the observed low-mass sequences. (C) 1995 American Astronomi
