cds-question@unistra.freclipsing-binary-starsphotometryvisible-astronomyEBLM J0113+31 is a moderately bright (V=10.1), metal-poor ([Fe/H]~-0.3) G0V star with a much fainter M dwarf companion on a wide, eccentric orbit (=14.3d). We have used near-infrared spectroscopy obtained with the SPIRou spectrograph to measure the semi-amplitude of the M dwarf's spectroscopic orbit, and high-precision photometry of the eclipse and transit from the CHEOPS and TESS space missions to measure the geometry of this binary system. From the combined analysis of these data together with previously published observations, we obtain the following model-independent masses and radii: M_1_=1.029+/-0.025M_{sun}_, M_2_=0.197+/-0.003M_{sun}_, R_1_=1.417+/-0.014R_{sun}_, R_2_=0.215+/-0.002R_{sun}_. Using R_1_ and the parallax from Gaia EDR3 we find that this star's angular diameter is {theta}=0.0745+/-0.0007mas. The apparent bolometric flux of the G0V star corrected for both extinction and the contribution from the M dwarf (<0.2 per cent) is F_{Earth}_=(2.62+/-0.05)x10^-9^erg/cm^2^/s. Hence, this G0V star has an effective temperature T_eff,1_=6124K+/-40K (rnd.) +/-10K(sys.). EBLM J0113+31 is an ideal benchmark star that can be used for 'end-to-end' tests of the stellar parameters measured by large-scale spectroscopic surveys, or stellar parameters derived from asteroseismology with PLATO. The techniques developed here can be applied to many other eclipsing binaries in order to create a network of such benchmark stars.2022MNRAS.513.6042Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/513/6042CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/513/6042https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/513/6042http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/513/6042https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/513/6042https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/513/6042http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/513/6042GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/513/6042/lc01Data from archive file CH_PR100037_TG011601_V0200recnoRecord number assigned by the VizieR team.
