cds-question@unistra.frmultiple-starsspectroscopic-binary-starsThe study of a selected set of 69 double-lined spectroscopic binaries (SB2) with well defined visual and spectroscopic orbits was carried out. The orbital parallax, the mass, the colour, and the luminosity of each component were derived from observational data for almost all of these systems. We have also obtained an independent estimation of the component masses by comparing the colour-luminosity diagram (CMD) to the stellar evolution tracks reported by Pietrinferni. Nearly all of the observational points on the CMD are located between two tracks of slightly different mass or which fall very close to the one corresponding to a unique mass value. The masses obtained from the stellar model are in good agreement with their empirical values determined by parallax techniques (orbital, dynamical, and Gaia). This means that our adopted model is rather reliable and can therefore be used to infer further information, such as the age of each component in the studied systems. Our results indicate a fair correspondence between the age of primaries and secondary stars within 3{sigma}. Nevertheless, we caution that these age indications suffer of uncertainties due to both inhomogeneities/low precision of the adopted photometric data and possible systematics. Finally, it is statistically shown that along with the orbital and trigonometric parallaxes, the dynamical parallax can serve as a reliable tool for distance estimates.2020MNRAS.492.2709Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/492/2709CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)B/sb9 : SB9: 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/492/2709https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/492/2709http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/492/2709https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/492/2709https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/492/2709http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/492/2709GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/492/2709/table1 (ORB6 & SB9 common orbital elements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/492/2709/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/492/2709/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/492/2709/table1?GETtext/xml+votable180.050000true2.096916129.09043110.0055555555555555566/351 689 845 1397 1447 1504 1704 2317 2323 2340 2593 3176 4181 4316 5362 5802 8255 9072 9503 9570 9607 11109 12311 12390 12408 14084 14232 14441 14525 14786 15132 15562 15760 15906 16105 16268 16302 16678 17513 17875 17965 18889 19682 19921 20322 21568 22762 23538 23658 29784 30014 30833 31073 31751 31760 32516 32549 32597 32812 36072 36621 36742 40823 41763 44891 48104 49015https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/492/2709?format=asciidefaultJ/MNRAS/492/2709/table1ORB6 & SB9 common orbital elementsrecnoRecord number assigned by the VizieR team.
