cds-question@unistra.fropen-star-clusterslate-type-starschemical-abundancesStellar kinematic groups are kinematical coherent groups of stars that might have a common origin. These groups are dispersed throughout the Galaxy over time by the tidal effects of both Galactic rotation and disc heating, although their chemical content remains unchanged. The aim of chemical tagging is to establish that the abundances of every element in the analysis are homogeneous among the members. We study the case of the Hyades Supercluster to compile a reliable list of members (FGK stars) based on our chemical tagging analysis. For a total of 61 stars from the Hyades Supercluster, stellar atmospheric parameters (Teff, logg, {ksi}, and [Fe/H]) are determined using our code called StePar, which is based on the sensitivity to the stellar atmospherics parameters of the iron EWs measured in the spectra. We derive the chemical abundances of 20 elements and find that their [X/Fe] ratios are consistent with Galactic abundance trends reported in previous studies. The chemical tagging method is applied with a carefully developed differential abundance analysis of each candidate member of the Hyades Supercluster, using a well-known member of the Hyades cluster as a reference (vB 153). We find that only 28 stars (26 dwarfs and 2 giants) are members, i.e. that 46% of our candidates are members based on the differential abundance analysis. This result confirms that the Hyades Supercluster cannot originate solely from the Hyades cluster.2012A&A...547A..13Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/547/A13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/547/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/547/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/547/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/547/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/547/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/547/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/547/A13/stars (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/547/A13/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/547/A13/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/547/A13/stars?GETtext/xml+votable180.050000true44.444458329.66145830.0055555555555555566/60 336 340-341 377 411 428 712 890 892 917 1603 4079 4344 4444 4642 5009 5067 5590 5872 6418 6831 7314 7542 8009 8342 9459 10325 12465 13778 14426 14692 15227 15373 16986 17219 17391 17731 19108 20776 21874 22036 23546 23932 24117 25512 25793 26429 27014 27374 27385 27616 27791 28245 28432 29084 36288 40563 40892 40932 44652 48923https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/547/A13?format=asciiOpticaldefaultJ/A+A/547/A13/starsCombined table from original tablesNameStar namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
