cds-question@unistra.frmultiple-starsdwarf-starsOur goal is to find previously unknown binary systems among low-mass dwarfs in the solar neighborhood and to test the search technique. The basic ideas are to reveal the images of stars with significant ellipticities and/or asymmetries compared to the background stars on CCD frames and to subsequently determine the spatial parameters of the binary system and the magnitude difference between its components. For its realization we have developed a method based on an image shapelet decomposition. All of the comparatively faint stars with large proper motions (Vmag>13^m^, {mu}>300mas/yr) for which the 'duplicate source' flag in the Gaia DR1 catalogue is equal to one have been included in the list of objects for our study. As a result, we have selected 702 stars. To verify our results, we have performed additional observations of 65 stars from this list with the Pulkovo 1-m 'Saturn' telescope (2016-2017). We have revealed a total of 138 binary candidates (nine of them from the `Saturn' telescope and SDSS data). Six program stars are known binaries. The images of the primaries of the comparatively wide pairs WDS 14519+5147, WDS 11371+6022, and WDS 15404+2500 are shown to be resolved into components; therefore, we can talk about the detection of triple systems. The angular separation {rho}, position angle, and component magnitude difference {Delta}m have been estimated for almost all of the revealed binary systems. For most stars 1.5''<{rho}<2.5'', while {Delta}m<1.5^m^.2018AstL...44..103Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/44/124CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)I/298 : LSPM-North Catalog (Lepine+ 2005)I/333 : URAT Parallax Catalog (UPC) (Finch+, 2016)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/44/124https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/44/124http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/44/124https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/44/124https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/44/124http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/44/124GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/44/124/sdss-bc (SDSS binary candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/44/124/sdss-bc?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/44/124/sdss-bc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/44/124/sdss-bc?GETtext/xml+votable180.050000true0.7960866673.8452696670.005555555555555556Cone search capability for table J/PAZh/44/124/sasdssbc ("Saturn" telescope and SDSS binary candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/44/124/sasdssbc?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/44/124/sasdssbc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/44/124/sasdssbc?GETtext/xml+votable180.050000true58.60179555611.0656007220.005555555555555556Cone search capability for table J/PAZh/44/124/sat-bc (Pulkovo 1-m "Saturn" telescope binary candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/44/124/sat-bc?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/44/124/sat-bc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/44/124/sat-bc?GETtext/xml+votable180.050000true58.60255083311.0649045830.0055555555555555566/719 765 924 949 1686 1763 2696 2818 3621 4656 4907 4977 5630 5633 5692 5703 5802 5843 6055 6102 6105 6397 6464 6480 6586 7310 7334 7425 7506 7558 7587 7605 7844 7846 8228 8485 8605 8633 8677 8679 8944 8974 8978 9072 9160 9321 9332 9454 9499 9553 9744 9757 9802 9806 9807 9867 9999 10001 10027 10032 10314 10351 10452 10454 10654 10873 10886 10892 10921 10984 11058 11144 11184 11323 11477 11506 11683 13435 13437 13462 13679 13807 13913 14316 15425 18106 18107 18791 18883 19447 19469 19546 19603 19605 19628 19658 19717 19767 19847 19917 20046 20047 20081 20099 20239 20308 20395 20425 22341 22385 22517 23227 23270 23356 23465 23470 23660 27007 27473 27505 27662 27680 27823 27856 27859 27910 28071 28430 28472 28508 28511 28646 31672 32100 32124 32125 32127 32158 32190 32224 325528.650015785639275e-20 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/44/124?format=asciidefaultJ/PAZh/44/124/sdss-bcSDSS binary candidatesdm?
