cds-question@unistra.frmultiple-starssolar-system-planetsWe present results of a reconnaissance for stellar companions to all 131 radial velocity-detected candidate extrasolar planetary systems known as of 2005 July 1. Common proper-motion companions were investigated using the multi-epoch STScI Digitized Sky Surveys and confirmed by matching the trigonometric parallax distances of the primaries to companion distances estimated photometrically. We also attempt to confirm or refute companions listed in the Washington Double Star Catalog (<I/237>), in the Catalogs of Nearby Stars Series by Gliese and Jahreiss (<V/70>, in Hipparcos results (<I/239>, and in Duquennoy & Mayor's radial velocity survey (1991A&A...248..485D). Our findings indicate that a lower limit of 30 (23%) of the 131 exoplanet systems have stellar companions. We report new stellar companions to HD 38529 and HD 188015 and a new candidate companion to HD 169830. We confirm many previously reported stellar companions, including six stars in five systems, that are recognized for the first time as companions to exoplanet hosts. We have found evidence that 20 entries in the Washington Double Star Catalog are not gravitationally bound companions. At least three (HD 178911, 16 Cyg B, and HD 219449), and possibly five (including HD 41004 and HD 38529), of the exoplanet systems reside in triple-star systems. Three exoplanet systems (GJ 86, HD 41004, and Cep) have potentially close-in stellar companions, with planets at roughly Mercury-Mars distances from the host star and stellar companions at projected separations of 20AU, similar to the SunUranus distance. Finally, two of the exoplanet systems contain white dwarf companions. This comprehensive assessment of exoplanet systems indicates that solar systems are found in a variety of stellar multiplicity environments - singles, binaries, and triples - and that planets survive the post-main-sequence evolution of companion stars.2006ApJ...646..523Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/646/523CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/237 : Washington Visual Double Star Catalog, 1996.0 (Worley+ 1996)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)V/70 : Nearby Stars, Preliminary 3rd Version (Gliese+ 1991)J/A+A/398/363 : Statistical properties of exoplanets II (Santos+, 2003)J/MNRAS/372/1117 : SuperWASP exoplanetary transit survey (Christian+, 2006)J/A+A/479/865 : CoRoT exoplanet candidates (Loeillet+, 2008)J/ApJ/646/505 : Catalog of nearby exoplanets (Butler+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/646/523https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/646/523http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/646/523https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/646/523https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/646/523http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/646/523GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/646/523/table1 (Sample list of exoplanet systems searched for companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/646/523/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/646/523/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/646/523/table1?GETtext/xml+votable180.050000true164.6199158-10.7703850.005555555555555556Cone search capability for table J/ApJ/646/523/table3 (WDS entries that are not gravitationally bound companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/646/523/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/646/523/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/646/523/table3?GETtext/xml+votable180.050000true9.840858921.25047250.005555555555555556Cone search capability for table J/ApJ/646/523/table2 (Exoplanet systems with stellar companions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/646/523/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/646/523/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/646/523/table2?GETtext/xml+votable180.050000true1.5799167-49.07519440.0055555555555555566/679 748 871 1597 2110 2254 2312 2472 4136 4429 5009 5522 5718 6760 6791 6831 7240 7746 8357 8843 9403 9459 9843 11473 12030 12146 12465 12644 12899 14412 14416 14419 14466 14525 14548 15174 16213 16652 17341 17496 17730 17954 18496 18614 18688 18821 19904 19912 20145 21838 22036 22252 22518 22590 22878 23013 23030 23201 23681 24019 24178 25939 26183 26575 26706 27018 27088 27616 27750 27975 28130 28548 28763 29513 29541 30015 30526 31374 32848 32930 33243 33377 33630 33717 33923 34069 34905 34951 35079 35362 35442 36697 37018 37461 37573 37954 37955 38545 38728 39257 39280 39364 39646 39675 40101 40442 40985 41446 41607 41724 42044 42248 42333 42510 42760 43012 43228 43813 43818 43911 44243 44398 45364 45865 46297 46306 46800 46967 48105 48545https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/646/523?format=asciidefaultJ/ApJ/646/523/table1Sample list of exoplanet systems searched for companionsrecnoRecord number assigned by the VizieR team.
