Solid lines show the evolution tracks for α_cgm = 0.62 and α_mlt = 1.68 and a mass of 2.65 M_⊙. The dotted lines correspond to the same mass but α_cgm = 0.77 and α_mlt = 1.98. The solar-calibrated models for convection do not fit the observations. Dashed line and dot-dashed lines are 1.85 M_⊙ models, respectively, for α_cgm = 0.77 and α_cgm = 0.62. The smaller radius object is ξ Hya and the larger one ϵ Oph.
