cds-question@unistra.frmultiple-starsstellar-massesIn the Sixth Catalog of Orbits of Visual Binary Stars we found those belonging to the Main Sequence to form a sample containing 432 visual binaries. Their total masses were obtained dynamically, i.e. they were calculated using the orbital elements and the new Hipparcos parallaxes. For the same pairs the total mass was also found astrophysically - by applying the mass-luminosity relation. The apparent magnitudes of the components were found in two different ways: by deriving them from total magnitudes and magnitude differences, and by taking their values directly from a catalogue. The results for these two approaches show no essential discrepancy. The values of total masses obtained dynamically have a large dispersion involving even completely unrealistic values. This is a clear indication that the input data are not sufficiently reliable. Nevertheless, in a large number of cases the agreement between total masses obtained by us in two different ways is quite satisfactory indicating that i) for many visual binaries, as a rule not too distant and with high-quality orbital elements, the dynamical total masses can be reliable; ii) the mass-luminosity relation yields quite satisfactory estimates for the component masses when they belong to the Main Sequence and iii) a correlation between the relative parallax error and orbit grade exists.2010SerAJ.180...71Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Ser/180.71CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)V/39 : 4th Catalog of Orbits of Visual Binaries (Worley+, 1983)http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/wds/orb6 :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Ser/180.71https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Ser/180.71http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Ser/180.71https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Ser/180.71https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Ser/180.71http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Ser/180.71GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Ser/180.71/binaries (Input data on binaries and calculated masses)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Ser/180.71/binaries?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Ser/180.71/binaries?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Ser/180.71/binaries?GETtext/xml+votable180.050000true0.540188627.08448920.0055555555555555566/9 188 340 351 475 486 603 708 752 795 900 1040 1074 1165 1771 1855 1939 2036 2060 2460 2476 2520 2737 2881 2923 2940 2970 3006 3020 3083 3118 3196 3199 3285 3420 3460 3491 3570 3594 3650 3723 3756 3838 4316 4358 4670 4698 4920 5157 5255 5299 5498 5501 5590 5592 5670 5763 5802 5929 5994 6106 6147 6278 6340 6709 7117 7181 7264 7595 8237 8345 8348 8354 8597 8610 8690 8790 8822 9032 9072 9096 9442 9570 9642 9712 9857 9873 9875 10225 10433 11204 11290 12250 12330 12348 12390 12408 12509 12774 12798 12965 13115 13140 13301 13308 13477 13690 13723 13973 14266 14277 14459 14522 14525 14549 14582 14647 14753 14862 14908 14918 15154 15330 15371 15373 15428 15686 15861 15906 16105 16186 16415 16569 16678 16694 16792 16862 17067 17112 17141 17200 17248 17429 17462 17513 17611 17844 17955 17965 18127 18224 18441 18594 18654 18660 19105 19288 19320 19401 19417 19525 19817 19823 19881 20020 20071 20278 20499 20543 20703 20776 21015 21046 21052 21089 21136 21175 21228 21431 21519 21538 21568 21645 21937 22193 22201 22844 22854 22935 22979 22987 23005 23137 23191 23201 23410 23431 23444 23527 23535 23536 23538 23539 23655 23826 23869 23880 24023 24063 24159 24160 24212 24303 24582 24625 24673 24689 24797 25070 25113 25282 25297 25377 25577 25607 25649 25713 26174 26195 26478 26798 27581 27973 27980 28146 28153 28186 28481 28556 28700 28704 28797 28917 28934 29001 29281 29309 29385 29396 29490 29753 29784 29814 30416 30448 30675 30697 30716 30732 30833 30863 31061 31073 31121 31154 31281 31491 31742 31745 31751 31763 31944 32058 32229 32336 32516 32549 32551 32582 32619 32720 33334 33340 33366 33447 33689 33693 33809 33905 33922 34038 34052 34058 34075 34371 34481 34519 34624 34638 34738 34785 34789 34823 34896 34914 35033 35212 35216 35291 35689 35690 35814 35923 35948 36009 36069 36072 36074 36099 36285 36545 36742 37111 37338 37775 37790 37810 37902 37990 38168 38397 38573 38600 38814 38833 38834 38855 38862 39154 39275 39464 39654 39706 40046 40195 40688 40745 40755 40823 41288 41557 41607 41678 41740 41763 41855 41941 41973 42010 42181 42216 42285 42438 42442 42449 42459 42579 42889 43023 43072 43277 43372 43461 43498 43671 43723 43822 43852 43892 43959 44011 44033 44065 44082 44145 44284 44304 44329 44612 44626 44698 44778 44813 45516 45627 45685 45716 45773 45893 45934 46473 46845 46921 47008 47188 47210 47232 47249 47352 47457 47459 47541 47560 47579 47739 47742 47777 47919 47999 48004 48094 48199 48254 48273 48552 48749 48804 48946https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Ser/180.71?format=asciidefaultJ/other/Ser/180.71/binariesInput data on binaries and calculated massesplxParallaxmaspos.parallax.trigfloatNameStar namemeta.idcharrecnoRecord number assigned by the VizieR team.
