cds-question@unistra.frg-starsvariable-starsstellar-agesstellar-massesStudies using asteroseismic ages and rotation rates from star-spot rotation have indicated that standard age-rotation relations may break down roughly half way through the main sequence lifetime, a phenomenon referred to as weakened magnetic braking. Although rotation rates from spots can be difficult to determine for older, less active stars, rotational splitting of asteroseismic oscillation frequencies can provide rotation rates for both active and quiescent stars, and so can confirm whether this effect really takes place on the main sequence. We obtained asteroseismic rotation rates of 91 main sequence stars showing high signal-to-noise modes of oscillation. Using these new rotation rates, along with effective temperatures, metallicities and seismic masses and ages, we built a hierarchical Bayesian mixture model to determine whether the ensemble more closely agreed with a standard rotational evolution scenario, or one where weakened magnetic braking takes place. The weakened magnetic braking scenario was found to be 98.4% more likely for our stellar ensemble, adding to the growing body of evidence for this stage of stellar rotational evolution. This work presents a large catalogue of seismic rotation rates for stars on the main sequence, which opens up possibilities for more detailed ensemble analysis of rotational evolution with Kepler.2021NatAs...5..707Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NatAs/5.707CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NatAs/5.707https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NatAs/5.707http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NatAs/5.707https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NatAs/5.707https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NatAs/5.707http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NatAs/5.707GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NatAs/5.707/table1 (Asteroseismic rotation rates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NatAs/5.707/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NatAs/5.707/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NatAs/5.707/table1?GETtext/xml+votable180.050000true292.082695837.05983190.0055555555555555565/3734 3740 6/14578 14581 14585 14751 14757 14759 14763 14765 14767 14770-14771 14776 14778-14782 14819 14918 14921 14924 14929-14933 14935 14948 14959 14966-14967 14969-14970 15044 15057 15060-15062 15106-15107 15109 15112 15118 15120-15121 15123 15129-15131 15134 15145-15146 15149 15155-15156 15168 15171-15174 15178https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NatAs/5.707?format=asciidefaultJ/other/NatAs/5.707/table1Asteroseismic rotation ratesrecnoRecord number assigned by the VizieR team.
