Model of a planet with two constant density layers with M = 6.55 M_⊕ and R = 2.68 R_⊕. Values of k₂ (first row), normalized moment of inertia MoI (second row), and maximum surface deformation (third row, assuming M_S = 0.157 M_⊙ and a = 0.0143 AU in Eq. (18)), for ρ_m∕ρ = 0.73 (left column), and for ρ_m∕ρ = 0.01 (right column). Colors indicate the normalized density of the core. The color bar is logarithmic.
