cds-question@unistra.freclipsing-binary-starsm-starsphotometryvisible-astronomyEclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwarf component for which direct measurements of these stars' masses and radii are difficult using other techniques. Within the potential of M-dwarfs to be exoplanet host stars, the accuracy of theoretical predictions of their radius and effective temperature as a function of their mass is an active topic of discussion. Not only the parameters of transiting exoplanets but also the success of future atmospheric characterisation rely on accurate theoretical predictions. We present the analysis of five eclipsing binaries with low-mass stellar companions out of a sub-sample of 23, for which we obtained ultra high-precision light curves using the CHEOPS satellite. The observation of their primary and secondary eclipses are combined with spectroscopic measurements to precisely model the primary parameters and derive the M-dwarfs mass, radius, surface gravity, and effective temperature estimates using the PYCHEOPS data analysis software. Combining these results to the same set of parameters derived from TESS light curves, we find very good agreement (better than 1% for radius and better than 0.2% for surface gravity). We also analyse the importance of precise orbits from radial velocity measurements and find them to be crucial to derive M-dwarf radii in a regime below 5% accuracy. These results add five valuable data points to the mass-radius diagram of fully-convective M-dwarfs.2023MNRAS.519.3546Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/519/3546CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/549/A18 : WASP-30 and J1219-39 light + velocity curves (Triaud+, 2013)J/A+A/572/A50 : J0113+31 light + velocity curves (Gomez Maqueo Chew+, 2014)J/A+A/604/L6 : EBLM J0555-57 photometry and RV (von Boetticher+, 2017)J/A+A/625/A150 : 10 very-low-mass stars photometry (von Boetticher+, 2019)J/A+A/626/A119 : EBLM J2349-32 photometry, RV and spectra (Gill+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/519/3546https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/519/3546http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/519/3546https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/519/3546https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/519/3546http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/519/3546GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/519/3546/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/519/3546/list?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/519/3546/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/519/3546/list?GETtext/xml+votable180.050000true39.872083-20.040.0055555555555555566/6188 13663 21086 21108 36431 36468https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/519/3546?format=asciiOpticaldefaultJ/MNRAS/519/3546/j0239_01EBLM J0239-20 data from CH_PR100037_TG012001_V0200ContamFraction of flux in aperture from nearby starsinstr.backgrounddoubleSmearFraction of flux in aperture from readout trailsinstr.backgrounddoubleBgFraction of flux in aperture from backgroundinstr.backgrounddoubleTemp2thermFront_2 temperature sensor readingphys.temperaturefloatrecnoRecord number assigned by the VizieR team.
