Evolutionary tracks for selected Gaia FGK benchmark stars, interpolated in the Yonsei-Yale grid for three different combinations of mass (given in each panel) and metallicity (taken from Table 1), see text for meaning of line colours. Metallicities decrease from top to bottom. Effective temperature and luminosity determined in this paper are indicated by the black filled circles. The α-element abundances [α/Fe] of the grids are indicated as well.
