STAREVOL evolutionary tracks models in the (T_eff, ) space for main-sequence stars (solid lines) and post-main sequence stars (dashed-dot lines). The purple point represents the observed position of the star KOI-428 with the associated error bars in this space. The two best models are the green solid line with M _⋆  = 1.62   M_⊙ and the adopted one in dashed-dot red line with M _⋆  = 1.48   M_⊙ (see text).
