cds-question@unistra.fropen-star-clustersstellar-radiiRapidly rotating, low-mass members of eclipsing binary systems have measured radii that are significantly larger than predicted by standard evolutionary models. It has been proposed that magnetic activity is responsible for this radius inflation. By estimating the radii of low-mass stars in three young clusters (NGC 2264, NGC 2547, NGC 2516, with ages of ~5, ~35 and ~140Myr respectively), we aim to establish whether similar radius inflation is seen in single, magnetically active stars. We use radial velocities from the Gaia-ESO Survey (GES) and published photometry to establish cluster membership and then combine GES measurements of projected equatorial velocities with published rotation periods to estimate the average radii for groups of fast-rotating cluster members as a function of their luminosity and age. The average radii are compared with the predictions of both standard evolutionary models and variants that include magnetic inhibition of convection and starspots.2016A&A...586A..52Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/586/A52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/586/A52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/586/A52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/586/A52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/586/A52https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/586/A52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/586/A52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/586/A52/table1 (Photometric and spectroscopic data of GES Survey targets in clusters in NGC 2547, NGC 2516, NGC 22264 downloaded from the Edinburugh GES archive)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/586/A52/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/586/A52/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/586/A52/table1?GETtext/xml+votable180.050000true99.84983339.70044440.005555555555555556Cone search capability for table J/A+A/586/A52/table3 (Measured and calculated properties of cluster targets with resolved vsini and a reported rotation period)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/586/A52/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/586/A52/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/586/A52/table3?GETtext/xml+votable180.050000true122.1693-48.89380.0055555555555555565/9398 6/23636-23637 23639 37586-37587 39181 39183 39192 391941.1166583743361574e-19 3.3785437584409506e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/586/A52?format=asciidefaultJ/A+A/586/A52/table1Photometric and spectroscopic data of GES Survey targets in clusters in NGC 2547, NGC 2516, NGC 22264 downloaded from the Edinburugh GES archiveSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
