Comparison of AB Dor C with PMS theoretical models of Chabrier et al. (2000) (top) and Baraffe et al. (2015) (bottom). Isochrones (dashed lines) correspond to 10 (top isochrone), 50, and 100 Myr, in the case of the DUSTY models, and to 10 (top isochrone), 16, 25, 40, 50, and 100 Myr, in the case of BHAC15. Isomasses (solid lines), in both cases, are for 0.04 (rightmost isomass), 0.05, 0.07, 0.09, and 0.10 M_⊙.
