cds-question@unistra.frmultiple-starsvisible-astronomytrigonometric-parallaxstellar-massesUsing the method of apparent motion parameters, we have studied the relative motion of the components in 561 pairs of wide (rho>2") and relatively nearby (Hipparcos parallaxes >0.01") visual double stars based on data from the WDS catalog. The minimum masses of the double stars have been calculated at given parallaxes. We have identified 358 optical pairs. For 11 stellar pairs, we have found the minimum mass to exceed the estimate corresponding to their spectral types and luminosities. This excess is 5-7M_{sun}_ for two stars, ADS7446 and 9701.2008PAZh...34..446Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/34/446CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/237 : The Washington Visual Double Star Catalog, 1996.0 (Worley+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/34/446https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/34/446http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/34/446https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/34/446https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/34/446http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/34/446GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/34/446/table2 (Optical binaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/34/446/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/34/446/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/34/446/table2?GETtext/xml+votable180.050000true0.5527.08330.0055555555555555566/508 684 826 987 1201 1283 1296 1341 1504 1642 1728 2051 2167 2258 2345 2374 2455 2456 2549 2591 2697 2722 2737 2747 2872 2923 2924 2966 2973 3005 3118 3258 3363 3507 3689 3697 3729 3777 3809 3932 3986 4058 4181 4316 4444 4690 4762 4839 4881 4895 4920 5149 5207 5373 5413 5498 5538 5556 5645 5802 5853 6219 6273 6278 6409 6424 6454 6489 6752 6766 7136 7354 7413 7503 7665 7794 8466 8477 8534 8790 8845 8915 8985 9127 9403 9442 9476 10207 10255 10375 10486 10568 11385 11636 11732 12340 12390 12396 12418 12464 12610 12637 12798 12845 12864 12899 12944 13000 13243 13260 13282 13301 13392 13440 13766 13931 13960 14126 14218 14252 14266 14278 14375 14378 14380 14459 14515 14522 14607 14662 14687 14711 14814 14906 14994 15135 15170 15320 15362 15373 15522 15562 15585 15597 15602 15621 16069 16692 17965 17982 18005 18304 18330 18422 18455 18647 18688 18820 18907 18974 19025 19092 19156 19462 19554 19703 19868 19912 19923 20043 20078 20278 20310 20311 20322 20328 20513 20642 20872 21017 21175 21519 21531 21849 21940 22300 22613 22708 22773 22793 23369 23382 23410 23540 23582 23780 23818 23875 23974 24160 24536 24562 24656 24924 25364 25697 25735 25862 26024 26362 26538 26575 26625 26676 26929 26975 27322 27335 27403 27431 27661 27884 27919 27973 28191 28352 28482 28593 28784 28841 29196 29706 29842 29900 30015 30130 30339 30419 30458 30518 30529 30543 30665 30789 31475 31517 31716 31720 31751 31874 32001 32017 32070 32087 32124 32192 32288 32496 32561 32564 32678 32679 32970 33092 33230 33312 33890 33935 34096 34213 34519 34599 34966 34983 35014 36233 36344 36541 36778 37101 37178 37236 37591 37616 37617 37645 38064 38955 39000 40271 40515 40892 41051 41058 41089 41381 41412 41672 41724 41755 41757 41918 42010 42028 42087 42172 42622 43032 43141 43677 44088 44284 44411 44557 44649 44844 44998 45378 45613 45954 46129 46270 46640 47113 47417 47424 47463 47465 47643 47652 48023 48768 48923 49020https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/34/446?format=asciiOpticaldefaultJ/PAZh/34/446/table2Optical binariesrecnoRecord number assigned by the VizieR team.
