摘要：
The orbits of five single-lined spectroscopic binaries have recently been determined. We now use astrometric measurements that were collected with the Hi p par c os satellite to constrain the systems' mass ratios and secondary masses. The barycentric astrometric orbits of three binary systems, HD140667, HD158222, and HD217924, are fully determined and precise estimates of their mass ratios are obtained. Follow-up of these systems with infrared spectroscopy could yield model-independent dynamical masses for all components.
