cds-question@unistra.frmultiple-starsline-intensitiesspectroscopyWe present iron abundance analysis for 23 wide binaries with main sequence components in the temperature range 4900-6300K, taken from the sample of the pairs currently included in the radial velocity planet search on going at the Telescopio Nazionale Galileo (TNG) using the high resolution spectrograph SARG. The use of a line-by-line differential analysis technique between the components of each pair allows us to reach errors of about 0.02dex in the iron content difference. Most of the pairs have abundance differences lower than 0.02dex and there are no pairs with differences larger than 0.07dex. The four cases of differences larger than 0.02dex may be spurious because of the larger error bars affecting pairs with large temperature difference, cold stars and rotating stars.2004A&A...420..683Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/420/683CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/356/529 : Catalogue of wide binaries (Allen+ 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/420/683https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/420/683http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/420/683https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/420/683https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/420/683http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/420/683GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/420/683/stars (Star positions and magnitudes (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/420/683/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/420/683/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/420/683/stars?GETtext/xml+votable180.050000true20.01833336.6308330.0055555555555555566/548 1288 2284 3119 3319 3644 4734 8614 8952 10954 11267 12046 13297 13326 13710 14822 17441 18647 18748 23319 25466 40686 48915https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/420/683?format=asciiOpticaldefaultJ/A+A/420/683/hd030101Equivalent widths of HD 030101recnoRecord number assigned by the VizieR team.
