cds-question@unistra.frstellar-massesg-starsvisible-astronomyThe stellar rotation versus age relation is commonly considered a useful tool to derive reliable ages for Sun-like stars. However, in the light of Kepler data, the presence of apparently old and fast rotators that do not obey the usual gyrochronology relations led to the hypothesis of weakened magnetic breaking in some stars. In this letter, we constrain the solar rotation evolutionary track using solar twins. Predicted rotational periods as a function of mass, age, [Fe/H], and given critical Rossby number (Ro_crit_) were estimated for the entire rotational sample. Our analysis favours the smooth rotational evolution scenario and suggests that if the magnetic weakened breaking scenario takes place at all, it should arise after Ro_crit_>~2.29 or ages >~5.3Gyr (at 95 per cent confidence level).2019MNRAS.485L..68Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/485/L68CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/485/L68https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/485/L68http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/485/L68https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/485/L68https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/485/L68http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/485/L68GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/485/L68/table1a (Relevant parameters of solar twins stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/485/L68/table1a?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/485/L68/table1a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/485/L68/table1a?GETtext/xml+votable180.050000true6.1772844-53.98399830.005555555555555556Cone search capability for table J/MNRAS/485/L68/table1b (Relevant parameters for our rotation of solar twins stars analysed in this paper (selected sample))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/485/L68/table1b?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/485/L68/table1b?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/485/L68/table1b?GETtext/xml+votable180.050000true6.1772844-53.98399830.0055555555555555566/222 548 4128 4206 4665 8614 14757 15104 15139 15157 17301 17572 17587 17721 17929 18373 20593 21114 21177 21516 23583 23661 23873 29900 30878 30894 31029 31334 31433 34983 38279 38562 39557 39570 39576 39693 39801 40105 40892 43327 43845 43929 46056 47194 48310 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/485/L68?format=asciiOpticaldefaultJ/MNRAS/485/L68/table1aRelevant parameters of solar twins starsSimbadNameSimbad column added by the CDSmeta.idcharnullableNameStar namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
