cds-question@unistra.frspectroscopic-binary-starsproper-motionsvisible-astronomytrigonometric-parallaxstellar-massesWe have surveyed a sample of 165 solar-type spectroscopic binaries (SB) with periods from 1 to 30 days for higher-order multiplicity. 62 targets have been observed with the NACO adaptive optics system and 13 new physical tertiary companions were detected. Another 12 new wide companions (5 still tentative) were retrieved from the 2MASS (<II/246>) sky survey. Our binaries belong to 161 stellar systems; of these 64 are triple, 11 quadruple and 7 quintuple. After correction for incomplete detection, the fraction of SBs with additional companions is 63+/-5%. We find that this fraction is a strong function of the SB period P, reaching 96% for P<3d and dropping to 36% for P>12d. Period distributions of SBs with and without tertiaries are significantly different, but their mass ratio distributions are identical. New statistical data on the multiplicity of close SBs indicate that their periods and mass ratios were established very early, but periods of SBs within triples were further shortened by angular momentum exchange with companions.2006A&A...450..681Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/450/681CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/450/681https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/450/681http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/450/681https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/450/681https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/450/681http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/450/681GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/450/681/table2 (Object list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/450/681/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/450/681/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/450/681/table2?GETtext/xml+votable180.050000true3.12514.563610.0055555555555555566/325 404 493 535 725 845 863 924 998 1032 1045 1064 1077 1940 2051 2062 2075-2076 2127 2133 2317 2597 3094 3208 3626 4227 4241 4356 4566 4895 5343 5377 5398 5476 5488 5498 5592 5731 5772 5777 6147 6783 7075 7244 7390 7444 8060 8669 8935 9247 9442 10479 10481 10485 11275 11302 11508 11534 11636 11770 12012 12266 12303 12400 12784 12798 13136 13308 13440 13573 13802 13947 13966 14173 15195 15243 15770 15861 16302 16338 17058 17731 17965 18311 18537 18688 18889 19097 19670 19766 20286 20365 20428 21536 21790 23191 23495 23523 23527 23960 24037 24195 24256 24902 25074 25229 25521 26031 26048 26158 26753 26788 27352 29311 29604 29793 30219 30558 30703 30995 31472 31613 31666 31984 32067 32070 32158 32211 32617 33201 33447 33689 33966 35150 35196 35347 35485 37616 38117 40012 40131 41272 41295 41972 42034 42319 43850 44226 44924 45249 46065 46363 46790 47904 48169 48254 48455 48613 48933https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/450/681?format=asciiOpticaldefaultJ/A+A/450/681/table2Object listPlxParallaxmaspos.parallaxfloatrecnoRecord number assigned by the VizieR team.
