Radial mass fractions of the H–He mixture, water, and rock of Uranus models using P_V (left panel) and P_H (right panel). The solid, dashed, and dotted curves show the mass fraction of different models. In the left panel, the solid and dashed curves show the most extreme models in terms of rock and water mass fractions, whereas the dotted curves mark an in-between model. The gray- and blue-colored areas mark the average of the convective and non-convective regions of the presented models.
