Radius evolution as a function of time for a M_p = 10 M_⊕ planet, comparing capped and extrapolated radiative opacities. The blue lines represent a model with a composition gradient, while the orange lines show a model with flat composition profile. Both models assume a bulk heavy-element mass fraction of Z = 95. Lighter shades indicate the evolution using the extrapolated opacity method and darker shades indicate the evolution using the capped opacity method for out of table values.
