cds-question@unistra.fropen-star-clustersinfrared-photometryproper-motionsWe present the results of a deep wide-field near-infrared survey of 12deg^2^ of the Pleiades conducted as part of the United Kingdom Infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Galactic Cluster Survey (GCS). We have extracted over 340 high-probability proper motion (PM) members down to 0.03M_{sun}_ using a combination of UKIDSS photometry and PM measurements obtained by cross-correlating the GCS with data from the Two Micron All Sky Survey, the Isaac Newton Telescope and the Canada-France-Hawaii Telescope. Additionally, we have unearthed 73 new candidate brown dwarf (BD) members on the basis of five-band UKIDSS photometry alone. We have identified 23 substellar multiple system candidates out of 63 candidate BDs from the (Y-K, Y) and (J-K, J) colour-magnitude diagrams, yielding a binary frequency of 2844 per cent in the 0.075-0.030M_{sun}_ mass range.2007MNRAS.380..712Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/380/712CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/100/607 : Pleiades very low mass proper motion members (Hambly+ 1993)J/A+A/323/139 : K magnitude of Pleiades low-mass binaries (Bouvier+ 1997)J/A+A/329/101 : Masses of Pleiades members (Raboud+ 1998)J/A+A/335/183 : Pleiades low-mass stars rotational velocities (Queloz+ 1998)J/MNRAS/313/347 : Pleiades low-mass stars and brown dwarfs (Pinfield+, 2000)J/A+A/400/891 : IZ photometry of Pleiades brown dwarfs (Moraux+, 2003)J/MNRAS/342/1241 : Low-mass stars in M45 and M44 (Pinfield+, 2003)J/MNRAS/373/95 : ZYJHK survey of Upper Sco association (Lodieu+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/380/712https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/380/712http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/380/712https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/380/712https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/380/712http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/380/712GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/380/712/stars (observed Pleiade stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/380/712/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/380/712/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/380/712/stars?GETtext/xml+votable180.050000true55.164416723.4430.005555555555555556Cone search capability for table J/MNRAS/380/712/tablef1 (*Near-infrared (ZYJHK) photometry for 36 photometric low-mass multiple system candidates below K=13.5mag, corresponding to masses of 0.135M_{sun}_ in the Pleiades)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/380/712/tablef1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/380/712/tablef1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/380/712/tablef1?GETtext/xml+votable180.050000true55.420416725.90669440.0055555555555555565/115 118 6/451 454-455 459 464 466-467 476 478 487 496-498 500https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/380/712?format=asciiInfrareddefaultJ/MNRAS/380/712/starsobserved Pleiade starsrecnoRecord number assigned by the VizieR team.
