The Pulkovo Catalog of the Orbits Obtained for the Visual Binary and Multiple Stars by the Apparent Motion Parameters Method

Orbits of 69 wide pairs of visual binary and multiple stars are obtained by the apparent motion parameters (AMP) method. Orbits for 45 pairs are found based on Gaia DR3 data. Other pairs are investigated using Pulkovo observation rows and literary data. Out of 69 pairs, 59 have an orbital semi-major axis exceeding 100 au, while families of orbits are derived for 17 pairs. Comparative analysis of orbits with observations has been conducted. Average errors of orbital elements do not exceed 15–20%.
