Core mass (solid lines) and total mass of metals (dashed lines) of WASP-10b interior models with solar metallicity envelope, both in M_⊕. The models differ in the onset of the adiabatic interior as parametrised by the pressure level P_ad. The observed transit radius of this work requires to increases the total mass of metals by  ~300   M_⊕ compared to the larger radius from the discovery paper.
