cds-question@unistra.fropen-star-clustersmultiple-starsproper-motionsphotometryWe look for common proper motion companions to stars of the nearby young {beta} Pictoris moving group. First, we compiled a list of 185 {beta} Pictoris members and candidate members from 35 representative works. Next, we used the Aladin and STILTS virtual observatory tools and the PPMXL proper motion and Washington Double Star catalogues to look for companion candidates. The resulting potential companions were subjects of a dedicated astro-photometric follow-up using public data from all-sky surveys. After discarding 67 sources by proper motion and 31 by colour-magnitude diagrams, we obtained a final list of 36 common proper motion systems. The binding energy of two of them is perhaps too small to be considered physically bound. Of the 36 pairs and multiple systems, eight are new, 16 have only one stellar component previously classified as a {beta} Pictoris member, and three have secondaries at or below the hydrogen-burning limit. Sixteen stars are reported here for the first time as moving group members. The unexpected large number of high-order multiple systems, 12 triples and two quadruples among 36 systems, may suggest a biased list of members towards close binaries or an increment of the high-order-multiple fraction for very wide systems.2015A&A...583A..85Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/583/A85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/583/A85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/583/A85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/583/A85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/583/A85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/583/A85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/583/A85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/583/A85/tablea1 (Investigated {beta} Pictoris members and member candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A85/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A85/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A85/tablea1?GETtext/xml+votable180.050000true1.7086667-23.10755560.005555555555555556Cone search capability for table J/A+A/583/A85/tablea3 (Astrometry measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A85/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A85/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A85/tablea3?GETtext/xml+votable180.050000true4.929333319.853250.005555555555555556Cone search capability for table J/A+A/583/A85/tablea4 (Photometry measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A85/tablea4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A85/tablea4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A85/tablea4?GETtext/xml+votable180.050000true4.929333319.853250.005555555555555556Cone search capability for table J/A+A/583/A85/tablea5 (Common proper-motion companion candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/583/A85/tablea5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/583/A85/tablea5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/583/A85/tablea5?GETtext/xml+votable180.050000true24.3977917-6.76041670.0055555555555555566/129 419 431 483 518 674 722 759 765 850 939-940 942 1067 1245 1284 1738 1779 1782 2587 3750 4258 4271 4282 4468 5185 5224 5430 5677 5688 6060 6384 6490 7577 7829 7954 8723 12111 12260 12262-12263 12738 12886 13157 13450 13611 14458 15651 16455 16606 16719 17288 17291 17602 17605-17607 17744 17822 17887 18166 18760 18762 19043 19144 19219 19228 19536 19777 19812 19877 19888 20074 20257 20282 20591 20602 20618 20660 21049-21051 21202 21215 21277 21386 22231 22237 22289 22527 22773 22856-22857 22942 22950 22964 22966 23014 23028 23388 23509 23892 24096 24100 24102 24110 27706 27856 28395 28746 28784 28993 29187 29357 29519 30263 32830 33449 33477 33716 33849-33850 34054 34145 34244 35147 35169 35387 35447 36348 36543 36903 36909 37419 37769 38054 41295 41493 41537-41538 41565 41798 42096 42133 42176 42242 42249 42252 42272-42273 42483 42489 42910 43369 43372 44751 45238 45350-45351 45475 45746 45819-45820 46015 46922 47120-47121 47204-47205 47220 47249 47287 47345 47347 47486 47499 47626 47630 47652 47777-47778 47863 47911 47940-47941 47943 47948-47949 48038 48061 48250 48263 48274 48279 48318 48325 48349 48361 48363 48553 48648 48651 48905 489267.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/583/A85?format=asciiOpticaldefaultJ/A+A/583/A85/tablea2Unresolved or unidentified systemsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
