Hertzsprung Russel diagram (HRD) of young stars with disks in the Chamaeleon I region studied by Manara et al. (2016, 2017). The red diamonds and blue circles indicate L_⋆ computed with the distance of 160 pc found by Whittet et al. (1997) with our distance of 179 pc, respectively. Typical uncertainties are shown with a cross in the bottom left corner. The evolutionary models (isochrones in solid lines and evolutionarytracks with dashed lines) are taken from Baraffe et al. (2015).
