Abstract

The spectroscopic binaries HD 47415 and HD 210763 were observed with the Coudespectrographic telescope at Haute Provence. Data were analyzed to yield the orbital periods, radial velocities, component velocities, the ascending nodes, the eccentricities, the masses, and the separation distances. Comparisons with data from the David Dunlap and Mt. Wilson Observatories are provided. The 0.8 mass ratio and F8 IV and F5 IV primary spectral types detected indicate a main sequence F-type secondary.
