Description
We have obtained adaptive optics images and accurate radial velocities
for 7 very low mass objects, In the course of a long term effort to
determine accurate masses for very low mass stars (M<0.6 M_sun). We
use the new data, together with measurements from the litterature for
some stars, to determine new or improved orbits for these 7 systems.
They provide masses for 16 very low mass stars with accuracies that
range between 0.2% and 5%, and in some cases a very accurate distance as
well. This information is used in a companion paper to discuss the
Mass-Luminosity relation for the V, J, H and K photometric bands.
Observations collected at the European Southern Observatory -- ESO,
Chile, Laboratório Nacional de Astrofísica -- LNA, Brazil
