Description:
The spectroscopic orbits of single-lined binary dwarfs HD 23439B, HD
237287 and HD 217580 are derived from the radial velocities measured
with two correlation radial-velocity spectrometers: correlation radial
velocity (CORAVEL) at the 1m Swiss telescope of Observatoire de
Haute-Provence, and radial velocity meters (RVM) used on several
telescopes. The mutual agreement of these two data sets is analyzed
and found to be quite good. The estimated minimum mass of secondary
component corresponds to that of M-type dwarf for the first 2 systems
and is equal to 0.06 solar mass for HD 217580.
