Pebble growth tracks (a), their resulting pebble opacity (b), and produced dust opacity (c) for a standard set of model runs at 5 AU (see Table 1). The different lines indicate a range of planet masses, with the arrow indicating a logarithmic progression from 0.5− 20 M_⊕. The triangles indicate the location of the RCB, while the stars indicate the depth where the ambient temperature exceeds the sublimation temperature (2500 K) and the opacity from solids vanishes. The colors in the top panel show the ratio of the pebble size in the model relative to R_vlim (Eq. (14)). The colors in the two lower panels show the relative value of the indicated opacity to the total opacity.
