Catalog of orbits visual binary stars

Problem statement: The possibility of determining the AMPorbits of these pairs using Gaia DR3 data at the moment 2016.0 is considered. Results: 1) Orbits according to Gaia DR3 were obtained for 45 pairs. 2) For another 20 pairs, the quasi-instantaneous motion according to Gaia data contradicts the average motion from all available observations.

A possible reason is the presence of internal subsystems. 3) We also give AMP orbits for 3 bright stars (ADS 2080, ADS 7724, and ADS 9173) and 3 close pairs (less than 2": ADS 2416, ADS 5570, and T Tau NS) that do not have the Gaia DR3 positional observations. The basis for the study in cases 2 and 3 are the Pulkovo series of observations on the 26-inch refractor and/or data from the literature. Of the 69 pairs of stars studied, 59 have a semi-major axis of the orbit greater than 100AU.
