Boundaries of the evaporating layer: (R_min plus signs connected in purple and R_max, crosses connected in green) for Case A (fiducial case). We present the 16 stars of the hybrid model at 2 Myr by Baraffe et al. (2017). The dust is not evaporating where R > R_max and the dust-free region is located at R < R_min. Also we present an estimate of the lower threshold of inc where we expect models producing dips for each of the stars in the sample.
