cds-question@unistra.frspectroscopic-binary-starsdwarf-starsproper-motionsstellar-spectral-typesvisible-astronomytrigonometric-parallaxWe report the first results of a multi-epoch search for wide (separations greater than a few tens of AU), low-mass tertiary companions of a volume-limited sample of 118 known spectroscopic binaries within 30pc of the Sun, using the Two Micron All Sky Survey Point Source Catalog and follow-up observations with the KPNO and CTIO 4m telescopes. Note that this sample is not volume complete but volume limited, and, thus, there is incompleteness in our reported companion rates. We are sensitive to common proper motion companions with separations from roughly 200AU to 10000AU (~10"-->~10'). From 77 sources followed-up to date, we recover 11 previously known tertiaries, 3 previously known candidate tertiaries, of which 2 are spectroscopically confirmed and 1 rejected, and 3 new candidates, of which 2 are confirmed and 1 rejected. This yields an estimated wide tertiary fraction of 19.5^+5.2^_-3.7_%. This observed fraction is consistent with predictions set out in star formation simulations where the fraction of wide, low-mass companions to spectroscopic binaries is >10%.2012AJ....144...62Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/144/62CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2013)V/130 : Geneva-Copenhagen Survey of Solar neighbourhood III (Holmberg+, 2009)I/298 : LSPM-North Catalog (Lepine+ 2005)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/274 : Catalog of Components of Double & Multiple stars (Dommanget+ 2002)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)J/A+A/525/A95 : Search for brown-dwarf companions of stars (Sahlmann+, 2011)J/ApJS/190/100 : NIR proper motion survey using 2MASS (Kirkpatrick+, 2010)J/AJ/139/2566 : SLoWPoKES catalog (Dhital+, 2010)J/ApJS/181/62 : Survey of young solar analogs (Metchev+, 2009)J/AJ/137/1 : PMs and astrometry of late-type dwarfs (Faherty+, 2009)J/MNRAS/394/857 : UKIDSS-2MASS proper motion survey (Deacon+, 2009)J/A+A/450/681 : Companions to close spectroscopic binaries (Tokovinin+, 2006)J/AJ/126/3007 : Spectroscopy of faint red NLTT dwarfs (Reid+, 2003)J/AJ/121/2189 : Stars within 8pc of the Sun (Oppenheimer+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/144/62https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/144/62http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/144/62https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/144/62https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/144/62http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/144/62GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/144/62/table1 (Spectroscopic binary target list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/144/62/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/144/62/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/144/62/table1?GETtext/xml+votable180.050000true0.540208327.08450.005555555555555556Cone search capability for table J/AJ/144/62/table2 (Candidate and known common proper motion (CPM) companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/144/62/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/144/62/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/144/62/table2?GETtext/xml+votable180.050000true42.04041727.0736110.0055555555555555566/155 601 689 815 1077 1452 1504 1888 1969 2051 2127 2317 2381 2476 2597 3006 3783 4227 4241 4316 4670 4766 5176 5488 5498 5731 5802 6273 6340 6726 7205 8466 8663 8687 8788 8845 9072 9327 9442 10090 10225 10854 11109 11290 11534 11620 11636 12104 12330 12390 12864 13308 13440 13778 13802 13966 14512 14522 14693 15132 15243 15562 15861 15906 16105 16186 16213 16689 17058 17137 17860 17884 17965 18636 18734 19766 20278 20322 20940 21568 21790 21901 22300 23191 23246 23960 24902 25444 26462 26753 27268 27822 29784 31073 31101 31662 31751 31821 32067 32211 32372 34990 35150 35480 36742 38117 41272 41520 42758 43850 44833 44891 45164 46572 47825 48254 48589 48768https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/144/62?format=asciiOpticaldefaultJ/AJ/144/62/table1Spectroscopic binary target listSpTMK spectral type (2)src.spTypecharrecnoRecord number assigned by the VizieR team.
