cds-question@unistra.frmultiple-starsg-starsdwarf-starsA complete census of wide visual companions to nearby G-dwarf stars can be achieved by selecting candidates from the Two Micron All Sky Survey (2MASS) Point-Source Catalog and checking their status by second-epoch imaging. Such data are obtained for 124 candidates with separations up to 20", 47 of which are shown to be new physical low-mass stellar companions. A list of visual binaries with G-dwarf primaries is produced by combining newly found companions with historical data.2011AJ....141...52Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/52https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/141/52/table2 (Photometry and companion status)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/52/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/52/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/52/table2?GETtext/xml+votable180.050000true30.5503817-62.59204220.0055555555555555566/151 341 548 598 601 618 4227 4292 4645 8244 8297 8306 8366 8584 8612 8711 8743 8788 17721 17730 17872 20492 20495 20517 20597 20712 21013 21056 21076 21114 21162 21282 21326 21753 21784 21829 22289 22479 22630 22887 22989 23003 23150 23176 23181 23284 23410 23453 23728 23738 23953 23978 24130 24628 24633 24743 24790 24837 25115 25214 25313 25365 25397 25491 25636 25690 25692 25860 25998 26157 26180 26224 26300 26577 26669 26804 26898 26902 26935 26980 27122 27192 27305 27361 27391 27560 27728 27865 28009 28180 29374 29609 30720 30859 30983 31072 31144 31328 31416 31640 32299 32998 33029 33061 33086 33117 33137 33143 33188 33401 33488 33653 33831 33930 33945 33974 34152 34199 34231 34289 34310 34331 34338 34406 34521 34681 36001 36011 36072 36285 36412 36448 36449 36816 36834 36854 36889 36971 36977 36988 37021 37074 37121 37419 37422 37424 37450 37501 38304 38311 38333 38592 38813 38834 38866 38913 38985 39023 39025 39031 39064 39110 39126 39557 39562 39584 39621 39692 39718 39730 39954 40115 40271 40293 40386 40686 40901 40985 41023 41221 41259 41264 42918 43193 43428 43457 43533 43562 43677 43797 43858 43911 43962 44078 44123 44150 44220 44228 44401 44406 44486 44488 44549 44792 44887 44920 44951 450298.650015785639275e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/141/52?format=asciiOpticaldefaultJ/AJ/141/52/table2Photometry and companion statusrecnoRecord number assigned by the VizieR team.
