Scientific paper

The elements and masses of Mu Orionis and 9 Puppis have been determined using positional, astrometric, and spectroscopic data obtained following their periastron passages in 1985. For Mu Orionis, the results provide a period (P) of 18.53 yr, an inclination (i) of 97.6 deg, and an eccentricity (e) of 0.755. Elements obtained for 9 Puppis include P = 23.30 yr, i = 79.7 deg, and e = 0.730.
