cds-question@unistra.frg-starseffective-temperaturestellar-agesstellar-massesA new sample of solar analogs and twin candidates has been constructed and studied, paying particular attention to their light curves from NASA's Kepler mission. This Letter aims to assess their evolutionary status, derive their rotation and ages, and identify those which are solar analogs or solar twin candidates. We separate out the subgiants that compose a large fraction of the asteroseismic sample, and which show an increase in the average rotation period as the stars ascend the subgiant branch. The rotation periods of the dwarfs, ranging from 6 to 30 days and averaging 19 days, allow us to assess their individual evolutionary states on the main sequence and to derive their ages using gyrochronology. These ages are found to be in agreement with a correlation coefficient of r = 0.79 with independent asteroseismic ages, where available. As a result of this investigation, we are able to identify 34 stars as solar analogs and 22 of them as solar twin candidates.2014ApJ...790L..23Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/790/L23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/ApJ/749/152 : Asteroseismic analysis of 22 solar-type stars (Mathur+, 2012)J/MNRAS/423/122 : Abundances of 93 solar-type Kepler targets (Bruntt+, 2012)J/ApJS/210/1 : Asteroseismic study of solar-type stars (Chaplin+, 2014)J/ApJS/211/2 : Revised stellar properties of Q1-16 Kepler targetshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/790/L23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/790/L23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/790/L23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/790/L23https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/790/L23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/790/L23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/790/L23/table1 (Rotation of solar analogs and twin candidates revealed by Kepler)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/790/L23/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/790/L23/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/790/L23/table1?GETtext/xml+votable180.050000true292.6677237.989590.0055555555555555565/3776 6/14579 14581 14583 14585 14591 14733 14735 14752 14755 14757 14759 14763 14771 14777 14778 14781 14794 14827 14830 14918 14923 14926 14930 14932 14933 14936 14938 14939 14940 14941 14950 14958 14959 14960 14961 14964 14966 15040 15060 15110 15118 15119 15123 15129 15130 15131 15136 15140 15145 15146 15147 15156 15157 15158 15171 15172 15174https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/790/L23?format=asciidefaultJ/ApJ/790/L23/table1Rotation of solar analogs and twin candidates revealed by KeplerrecnoRecord number assigned by the VizieR team.
