Potential temperatures in simulations with constant (left, red curves), Bell and Lin (right, black curves), and Malygin opacities (right, green curve) for different values of . We note that both plots share the two legends. The r_s = 0.1 have N_c = 100 and correspond to the simulations shown in Fig. 12. A major difference between constant and Bell and Lin opacities is that close to the water-iceline at around there are indications of convective instability. The notion that this is related to the vicinity to the smoothing region is weakened, as the trend of inverted ϑ-profile continues as we deepen the potential in a well-resolved manner. The comparison to the more realistic Malygin et al. (2014)-opacities is done only for (compare the green and the straight black line). There, it is evident that the gradients in ϑ are weakened by a multi-step transition in κ.
