Scientific paper

The spectroscopic binaries HD 69148 and HD 85091 were observed at the Observatoire de Haute-Provence in order to determine their spectrographic orbits. Estimations of the spectral types of the secondaries and of the semi-major axis, deduced from the values of f(m) and a sin i, and of the spectral types of the primaries (G8 III et dG0 respectively), indicate that both systems are detached.
