cds-question@unistra.frmultiple-starsstellar-massesvisible-astronomytrigonometric-parallaxastrometryUsing the absolute astrometric positions and proper motions for common stars in the Hipparcos and Gaia catalogs separated by 24.75yr in the mean epoch, we compute mass ratios for long-period, resolved binary systems without any astrophysical assumptions or dependencies, except the presence of inner binary subsystems that may perturb the observed mean proper motions. The mean epoch positions of binary companions from the Hipparcos Double and Multiple System Annex are used as the first epoch. The mean positions and proper motions of carefully cross-matched counterparts in Gaia EDR3 comprise the second epoch data. Selecting only results with sufficiently high signal-to-noise ratio and discarding numerous optical pairs, we construct a catalog of 248 binary systems, which is published online. Several cases with unusual properties or results are also discussed.2021AJ....162..260Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/162/260CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/276 : Tycho Double Star Catalogue (TDSC) (Fabricius+ 2002)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/ApJS/224/19 : The KepVIM catalog (Makarov+, 2016)J/MNRAS/471/770 : Parameters & IR excesses of Gaia DR1 stars (McDonald+, 2017)J/AJ/157/136 : RVs of RGs with suspected massive companions (Makarov+, 2019)J/AJ/160/268 : Infrared photometry of binaries in Orion OB1 (Tokovinin+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/162/260https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/162/260http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/162/260https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/162/260https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/162/260http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/162/260GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/162/260/table1 (Star catalog of resolved binaries with astrometric mass ratios from Hipparcos & Gaia)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/162/260/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/162/260/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/162/260/table1?GETtext/xml+votable180.050000true1.195220338.17366920.0055555555555555566/447 601 1247 1692 2747 2856 2867 3003 3020 3199 3280 3410 3500 3537 3594 3751 3757 3863 3877 3914 4161 4163 4336 4504 4734 4834 5207 5255 5533 5590 5592 5691 5769 5994 6431 7310 8009 8296 8345 8750 8790 8896 9032 9154 9281 9294 9399 9857 9873 10090 10236 10313 10388 10459 10716 10747 10818 11029 11054 11118 11562 11620 11662 12471 12850 13053 13256 13323 13512 13609 13968 14393 14456 14459 14789 14850 14908 14973 15303 15311 15680 16011 16414 16494 16862 17462 18278 18376 18463 18647 19340 19390 19497 19645 20071 20081 20097 20143 20217 20428 20468 20605 20741 21228 21519 21907 22262 22661 23017 23182 23499 23526 23538 24557 24797 25070 25377 25481 25715 26026 26196 26391 26470 26610 26926 27629 27677 27973 28018 28295 28480 28486 28681 28942 29036 29196 29278 29313 29485 29597 29753 29899 30001 30186 30918 31132 31589 31621 31720 31742 31988 32058 32321 32763 32838 33100 33337 33922 33930 33943 34052 34058 34204 34258 34519 34737 34896 34942 35033 35081 35083 35290 35436 35509 35529 35628 35948 36009 36068 36099 36148 36544 36755 37022 37090 37714-37715 37778 37804 38191 38215 38374 38397 38500 38506 38724 38834 38855 39275 39405 39441 39464 39499 39660 39709 39780 40657 40980 41007 41410 41556-41557 41613 41707 42122 42347 42442 42512 42615 42903 43242 43851 43858 43889 44065 44916 45251 45602 45803 45805 45934 46302 46339 46394 46426 46480 46599 46797 47165 47188 47315 47541 47568 47776 47919 48579 48749 489231.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/162/260?format=asciiOpticaldefaultJ/AJ/162/260/table1Star catalog of resolved binaries with astrometric mass ratios from Hipparcos & Gaiaqmean[0.02/8.37] Median q from MC simulationsphys.mass;arith.ratiofloatSNR[10.8/53133] Signal-to-Noise ratiostat.snrdoubleSep[408/13327] Gaia EDR3 separation (J2016)maspos.angDistancedoublePA[1.1/360] Gaia EDR3 position angle (J2016)degpos.posAngfloatQ[1/3] Quality flag (1)meta.code.qualint_RAPosition from SIMBAD (right ascension part)degpos.eq.ra;meta.mainnullable_DEPosition from SIMBAD (declination part)degpos.eq.dec;meta.mainnullablerecnoRecord number assigned by the VizieR team.
