Fig. 4
Evolutionary tracks from Mowlavi et al. (2012) for slightly sub-solar initial metallicity (Z = 0.012). Dashed lines are isochrones for ages from 1 to 5 × 108 years. The gray regions correspond to tracks compatible with the dynamical masses estimated in Sect. 2. The colored boxes are the effective temperatures and stellar radii discussed in Sect. 3.
