Scientific paper

Orbital elements, as well as the dynamic parallaxes and masses, are derived for the visual binaries ADS 221 and ADS 1762. For ADS 221, the elements were calculated from 130 observations taken from the lists of the Naval Observatory and Hussey (1901), and from literature data. A dynamic parallax of 0.0111 arcsec is also obtained, which results in masses of 1.42 and 1.20 solar masses for the binary components. Corrected orbital elements for ADS 1762 were computed from those of Baize (1959) by the Kowalsky method, along with a dynamic parallax of 0.0081 arcsec which gives masses of 1.16 and 1.13 solar masses for the stars.
