cds-question@unistra.freclipsing-binary-starsvisible-astronomymedium-band-photometryradial-velocitySurface brightness - colour relations (SBCRs) are very useful tools for predicting the angular diameters of stars. They offer the possibility to calculate very precise spectrophotometric distances by the eclipsing binary method or the Baade-Wesselink method. Double-lined Detached Eclipsing Binary stars (SB2 DEBs) with precisely known trigonometric parallaxes allow for a calibration of SBCRs with unprecedented precision. In order to improve such calibrations, it is important to enlarge the calibration sample of suitable eclipsing binaries with very precisely determined physical parameters. We carefully chose a sample of ten SB2 DEBs in the solar neighbourhood which contain inactive main-sequence components. The components have spectral types from early A to early K. All systems have high-precision parallaxes from the Gaia mission. We analysed high precision ground- and space-based photometry simultaneously with the radial velocity curves derived from HARPS spectra. We used spectral disentangling to obtain the individual spectra of the components and used these to derive precise atmospheric parameters and chemical abundances. For almost all components, we derived precise surface temperatures and metallicities. We derived absolute dimensions for 20 stars with an average precision of 0.2% and 0.5% for masses and radii, respectively. Three systems show slow apsidal motion. One system, HD 32129, is most likely a triple system with a much fainter K6V companion. Also three systems contain metallic-line components and show strong enhancements of barium and ittrium. The components of all systems compare well to the SBCR derived before from the detached eclipsing binary stars. With a possible exception of HD 32129, they can be used to calibrate SBCRs with a precision better than 1% with available DR3 parallaxes.2022A&A...666A.128Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/666/A128CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/666/A128https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/666/A128http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/666/A128https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/666/A128https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/666/A128http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/666/A128GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/666/A128/table1 (Basic data on the eclipsing binary stars studied in the current work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/666/A128/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/666/A128/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/666/A128/table1?GETtext/xml+votable180.050000true62.9008333-20.35616670.0055555555555555566/5217 24108 25741 36184 38721 41150 43075 43659 45754 459423.322582951404819e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/666/A128?format=asciiOpticaldefaultJ/A+A/666/A128/table1Basic data on the eclipsing binary stars studied in the current workNameEclipsing binary star namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
