    Gaia FGK benchmark stars: Fundamental Teff and log g of the third version
    (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.

    Unravelling UBC 274: A morphological, kinematical, and chemical analysis of a disrupting open cluster
    (2022) Casamiquela, L.; Olivares, J.; Tarricq, Y.; Ferrone, S.; Soubiran, C.; Jofre, P.; di Matteo, P.; Espinoza-Rojas, F.; Castro-Ginard, A.; de Brito Silva, D.; Chaname, J.
    Context. Open clusters in the process of disruption help to understand the formation and evolution of the Galactic disk. The wealth and homogeneity of Gaia data have led to the discovery of several open clusters with signs of disruption. Detailed chemical information for these clusters is essential in order to study the timescales and interplay between the star formation process and cluster disruption.
