| Abstract: | Preliminary new orbital elements were computed for the visual binary stars A 1 ‐ ADS 1345, A 2629 ‐ ADS 3610, BU 560 ‐ ADS 4371, STF 3115 ‐ ADS 4376, STF 1426 AB ‐ ADS 7730 and STF 2437 ‐ ADS 11956. Using Straizys and Kuriliene's data, we derived new formulae for computing dynamical parallaxes for luminosity classes IV and V. The values found for those systems are in agreement with the Hipparcos parallaxes and the corresponding systemic masses are consistent with the spectral types. (© 2008 WILEY‐VCH Verlag GmbH & Co.
