Model of the internal structure of a giant planet hosting layered semi-convection. The red area represents the core, while the white one represents the gaseous envelope. Within the latter, double-diffusive convection acts to create a staircase-like profile for the density (in orange). Convective layers of vertical extent d are separated by infinitesimally thin stably stratified interfaces. The density undergoes a density jump by a value Δρ at each interface. The rotation axis Ω (in red) forms an angle Θ with respect to the gravity g (in blue), directed along the (Mz) direction.
