cds-question@unistra.frmultiple-starsproper-motionsvisible-astronomysloan-photometrystellar-distanceradial-velocityWe present a catalog of 80 very wide fragile binary candidates (projected separations >10000AU) from the Sloan Digital Sky Survey Data Release Eight spectral archive. The pairs were selected based on proper motion, radial velocity, metallicity, and photometric parallax criteria. The angular separations of these pairs range from 3" to 250". The peak in the metallicity distribution of these pairs is about -0.5dex of solar metallicity. Space motions and reduced proper motion diagrams indicate that all these pairs are members of the disk. The chromospheric activity index S_HK_ of each component in 38 binary candidates having spectra of high signal-to-noise ratio and member stars of three open clusters (NGC 2420, M67, and NGC 6791) were measured. The S_HK_ versus color relation for these binary candidates is consistent with the trend seen in these open clusters. The ages implied by this relation suggest that fragile wide pairs can survive longer than 8Gyr.2012AJ....143...31Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)I/298 : LSPM-North Catalog (Lepine+, 2005)I/121 : Common proper motions stars in AGK3 (Halbwachs, 1986)J/AJ/139/2566 : SLoWPoKES catalog (Dhital+, 2010)J/AJ/133/889 : Faint companions of Hipparcos stars (Lepine+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/143/31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/143/31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/143/31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/143/31https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/143/31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/143/31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/143/31/binaries (Properties of fragile binary candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/143/31/binaries?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/143/31/binaries?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/143/31/binaries?GETtext/xml+votable180.050000true214.82804170.43063890.0055555555555555566/904 2303 2644 4769 4772 4948 5811 6220 6404 6452 6496 6497 7248 7743 7781 8331 8392 9162 9517 10122 10700 11053 11059 11219 13329 14572 14573 15518 15541 15561 15775 15892 16156 16157 16181 16187 17750 17755 17758 17811 17981 18021 18025 18026 18076 18391 18777 19030 19033 19036 19753 19761 22512 22714 22719 23183 23188 23203 23210 23213 23354 24118 24119 24248 24400 25963 26168 26171 27236 27244 27455 27542 27580 32537 32699 36728 488832.85864675833786e-19 3.5010283109654867e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/143/31?format=asciiOpticaldefaultJ/AJ/143/31/binariesProperties of fragile binary candidatesSDSS-AFull SDSS-DR8 name, as in Cat.
