Evolutionary tracks on the log(T_eff)−log(g) plane of model stars of mass 2.5 M_⊙ (blue lines) and 2.6 M_⊙ (red lines), calculated by assuming different values of the overshoot parameter ζ. The green line refers to a 2.6 M_⊙ model star obtained by assuming ζ = 0.06 and an FST parameter β = 0.27. The grey and yellow rectangles indicate the error boxes for the two components of Capella given, respectively, in Torres et al. (2015) and Takeda et al. (2018).
