Top: radial profile of the aspect ratio h = H/r (black curve, left vertical axis) and midplane temperature T (red dashed curve, right vertical axis) in our disk model. Bottom: radial profile of the opacity κ. The plots show the state reached after a relaxation, with all the heating and cooling terms in balance. This is considered an equilibrium state prior to the follow-up simulations with embedded embryos. Vertical dotted lines indicate important changes in the disk structure, namely the snowline close to r ≃ 4 AU and the transition to the flared stellar-irradiated outer region near r ≃ 7 AU.
