cds-question@unistra.freclipsing-binary-starsvisible-astronomymedium-band-photometryRecent studies have shown that stellar chromospheric activity, and its effect on convective energy transport in the envelope, is most likely the cause of significant radius and temperature discrepancies between theoretical evolution models and observations. Accurate mass, radius, and abundance determinations from solar-type binaries exhibiting various levels of activity are needed for a better insight into the structure and evolution of these stars. We aim to determine absolute dimensions and abundances for the solar-type detached eclipsing binary EF Aqr, and to perform a detailed comparison with results from recent stellar evolutionary models.2012A&A...540A..64Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/540/A64CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/540/A64https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/540/A64http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/540/A64https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/540/A64https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/540/A64http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/540/A64GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/540/A64/photStromgren photometryJDJulian Datedtime.epochdoublerecnoRecord number assigned by the VizieR team.
