cds-question@unistra.frmultiple-starsorbitsThe paper presents orbits of 69 wide pairs of visual binary and multiple stars (part of 65 systems) obtained by the Apparent Motion parameters (AMP) method. 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. Among them, for 17 pairs, families of orbits with minimum periods from 5 thousand to 730 thousand years and minimum semi-major axes of more than 400AU were obtained. The only possible solutions were obtained for the orbits of 28 pairs. Of these, 20 pairs have a semi-major axis of the orbit greater than 100AU and periods from 600 to 6000 years. Relative errors in determining the elements are generally about 15-20%. The orientation of the resulting orbits in the galactic coordinate system is also determined.2025ARep...69..398Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ARep/69.398CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ARep/69.398https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ARep/69.398http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ARep/69.398https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ARep/69.398https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ARep/69.398http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ARep/69.398GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/ARep/69.398/table1 (Description of data on stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ARep/69.398/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ARep/69.398/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ARep/69.398/table1?GETtext/xml+votable180.050000true0.1430847-53.09771360.005555555555555556Cone search capability for table J/other/ARep/69.398/table5 (Initial Gaia DR3 data for each component)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ARep/69.398/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ARep/69.398/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ARep/69.398/table5?GETtext/xml+votable180.050000true0.14347869607-53.097798472360.0055555555555555566/342 1550 1642 2737 2747 3118 3280 4444 4597 5091 5498 5831 5986 6003 6154 6313 6522 7063 7264 7665 8093 8896 9083 9447 10004 10089-10090 10211 10313 10358 10420 10467 10721 10738 10741 10954 11436 11488 11500 11732 11969 12228 12264 12720 13301 14456 14459 15154 15174 15311 15457 15760 15812 16302 16338 17783 19778 20310 20428 23213 28395 32115 35330 36072 44999https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ARep/69.398?format=asciidefaultJ/other/ARep/69.398/table1Description of data on starsrecnoRecord number assigned by the VizieR team.
