cds-question@unistra.frlate-type-starsstellar-massesstellar-agesmetallicityIn recent years, there has been a push to understand how chemical composition affects the magnetic activity levels of main sequence low-mass stars. Results indicate that more metal-rich stars are more magnetically active for a given stellar mass and rotation period. This metallicity dependence has implications for how the rotation periods and activity levels of low-mass stars evolve over their lifetimes. Numerical modelling suggests that at late ages more metal-rich stars should be rotating more slowly and be more magnetically active. In this work, we study the rotation and activity evolution of low-mass stars using a sample of Kepler field stars. We use the gyro-kinematic age dating technique to estimate ages for our sample and use the photometric activity index as our proxy for magnetic activity. We find clear evidence that, at late ages, more metal-rich stars have spun down to slower rotation in agreement with the theoretical modeling. However, further investigation is required to definitively determine whether the magnetic activity evolution occurs in a metallicity dependent way.2024MNRAS.533.1290Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/533/1290CatalogResearchIsServedByTAP 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/MNRAS/533/1290https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/533/1290http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/533/1290https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/533/1290https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/533/1290http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/533/1290GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/533/1290/table1 (Properties of 7752 late-type stars in the Kepler field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/533/1290/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/533/1290/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/533/1290/table1?GETtext/xml+votable180.050000true291.2289436.741730.0055555555555555564/922-923 933-935 944-946 5/3645-3647 3683 3704 3706 3729-3731 3760 3788-3789 3792-3793 6/14567 14573 14575 14577-14579 14730-14731 14744 14746 14749-14751 14792 14794-14795 14822 14828 14830-14831 14914-14915 15044-15045 15056-15057 15059-15062 15160-15161 15176-15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/533/1290?format=asciidefaultJ/MNRAS/533/1290/table1Properties of 7752 late-type stars in the Kepler fieldrecnoRecord number assigned by the VizieR team.
