cds-question@unistra.frmultiple-starsbrown-dwarfsastrometrystellar-spectral-typesproper-motionsstellar-distancestellar-massesvisible-astronomyWe present the discovery of 255 binary and 6 multiple system candidates with wide (>5arcsec) separation composed by ultracool dwarfs (UCDs) companions to stars, plus nine double ultracool dwarf systems. These systems were selected based on common distance criteria. About 90 per cent of the total sample has proper motions available and 73 per cent of the systems also satisfy a common proper motion criterion. The sample of ultracool candidates was taken from the Dark Energy Survey (DES) and the candidate stellar primaries are from Gaia DR2 and DES data. We compute chance alignment probabilities in order to assess the physical nature of each pair. We find that 174 candidate pairs with Gaia DR2 primaries and 81 pairs with a DES star as a primary have chance alignment probabilities <5 per cent. Only nine candidate systems composed of two UCDs were identified. The sample of candidate multiple systems is made up of five triple systems and one quadruple system. The majority of the UCDs found in binaries and multiples are of early L type and the typical wide binary fraction over the L spectral types is 2-4 per cent. Our sample of candidate wide binaries with UCDs as secondaries constitutes a substantial increase over the known number of such systems, which are very useful to constrain the formation and evolution of UCDs.2020MNRAS.499.5302Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/499/5302CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)II/357 : The Dark Energy Survey (DES): Data Release 1 (Abbott+, 2018)J/MNRAS/489/5301 : DES Y3 substellar LT and M catalogs (Carnero Rosell+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/499/5302https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/499/5302http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/499/5302https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/499/5302https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/499/5302http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/499/5302GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/499/5302/table1 (The common distance pair candidates identified using the UCD combined to Gaia DR2 and DES DR1 data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/499/5302/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/499/5302/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/499/5302/table1?GETtext/xml+votable180.050000true0.46723-43.262636940.005555555555555556Cone search capability for table J/MNRAS/499/5302/table2 (The nine common distance pair candidates identified among the UCD and the letters A and B represent a different UCD)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/499/5302/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/499/5302/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/499/5302/table2?GETtext/xml+votable180.050000true0.87629111-0.1850450.005555555555555556Cone search capability for table J/MNRAS/499/5302/table3 (The common distance multiple systems found in our search)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/499/5302/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/499/5302/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/499/5302/table3?GETtext/xml+votable180.050000true2.27519-53.224933060.0055555555555555566/17357 17369 17375 17615 17630 17648 17663 17666 17699 17701 17725 17740 17752 17755 17767 17793-17794 17801 17810 17815 17826 17831 17833-17835 17856 17955 17970 17988 18006 18016-18017 18068 18082 18090-18091 18114-18115 18177 18759 18770 18793-18794 18832-18833 18848 18852 19020 19031 19033-19034 19037 19043 19049 19052 19056 19095 19120 33251 33275-33276 33397 33405 33499 33506-33507 33518 33520 33545 33551 33554 33556 33572 33581 33595-33596 33598 33611 33614 33633 33644 33657 33666 33679 33753 33768 33872 33887 33895 33898-33899 33937 33969 33974 34002 34014 34028 34036 34067 34081 34176 34307 34344 34353 34433 34493 34723 34727 34827 34830 34836 34847 34860 34874 34881 34889 34901 34952 34980 34983 34990 35000 35002-35003 35022 35027 35044 35046 35049 35060 35062 35093 35097 35102 35107 35182 35200 35329 35350 35363 35372 35381-35382 35490 35927 35935 36105 36605 36743 36761 36764 36781 36784 36797 36842 45436 45471 45510 45536-45537 45545 45551 45556 45683 45692 45695 45781 45828 45836 45839 45851 45867 45876 45878 45905-45906 45930-45931 45952 45955 45969 45977 45982 45998 46012 46018 46042 46044 46048 46058 46070 46085 46093 46098 46108 46110 46117 46128 46149-46150 46166 46178 46182 46189 46195 46206 46222-46223 46239 46255 46270 46278 46285 46288-46290 46294-46295 46313 46333 46364 46375 46383 46385 46402 46442 46450 46465 46468 46477 46479 46498 46503-46504 46514 46598 46604 46609 46624 46627 46632-46633 46668 46681 46691 46694 46704 46733 46740 46749 46757-46758 46761 47360 47365 47441-474421.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/499/5302?format=asciiOpticaldefaultJ/MNRAS/499/5302/table1The common distance pair candidates identified using the UCD combined to Gaia DR2 and DES DR1 datae_gmagA?
