    Fundamental effective temperature measurements for eclipsing binary stars - III. SPIRou near-infrared spectroscopy and CHEOPS photometry of the benchmark G0V star EBLM J0113+31
    EBLM 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 (= 14.3 d)...
