cds-question@unistra.freclipsing-binary-starsradial-velocityThe influence of stellar activity on the fundamental properties of stars around and below 1M_{sun}_ is not well understood. 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 V636Cen, and to perform a detailed comparison with results from recent stellar evolutionary models. uvby light curves and uvby{beta} standard photometry were obtained with the Stroemgren Automatic Telescope, radial velocity observations with the CORAVEL spectrometer, and high-resolution spectra with the FEROS spectrograph, all at ESO, La Silla. State-of-the-art methods were applied for the photometric and spectroscopic analyses.2009A&A...502..253Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/502/253CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/487/1081 : uvby photometry of 6 eclipsing binaries (Clausen+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/502/253https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/502/253http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/502/253https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/502/253https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/502/253http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/502/253GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/502/253/tablea1Radial velocities of V636 Cen and residuals from the final spectroscopic orbitrecnoRecord number assigned by the VizieR team.
