Accurate masses of very low mass stars. II. The very low mass triple system Gl 866.
DELFOSSE X., FORVEILLE T., UDRY S., BEUZIT J.-L., MAYOR M. and PERRIER C.
Abstract (from CDS):
We present very accurate orbital parameters and mass measurements (2.4% accuracy) for the well known very low mass triple system Gl 866. We obtain first orbital elements for the short-period orbit and greatly improve the long period orbit. All three stars have masses close to 0.1M☉, and the system thus provides the strongest constraints to date on the mass-luminosity relation close to the brown dwarf limit.
