Main- and post-main-sequence Dartmouth evolution tracks for a [Fe/H] of 0.15 dex (solid lines) and 0.5 dex (dashed lines). The 68.3%, 95.5%, and 99.7% confidence regions (from scenario 1) of the host star (KOI-1257 A) are superimposed in blue and those of the secondary star (KOI-1257 B) are superimposed in red. The tracks are not displayed after an age corresponding to the age of the Universe.
