    (2024) Soubiran, C.; Creevey, O. L.; Lagarde, N.; Brouillet, N.; Jofre, P.; Casamiquela, L.; Heiter, U.; Aguilera-Gomez, C.; Vitali, S.; Worley, C.; de Brito Silva, D.
    Context. Large spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to determine the atmospheric parameters of millions of stars. The Gaia FGK benchmark stars are reference stars with T-eff and log g derived through fundamental relations, independently of spectroscopy, to be used as anchors for the parameter scale. The first and second versions of the sample have been extensively used for that purpose, and more generally to help constrain stellar models.
