Vertical velocities in z-direction for planets on fixed circular orbits in fully radiative discs with different disc masses (from top to bottom) in the disc’s midplane: M_Disc = 0.005 M_⊙, M_Disc = 0.015 M_⊙ and M_Disc = 0.04 M_⊙. The disruption in the velocity patterns for the higher mass discs are caused by convection inside the disc. A positive velocity simulates outward flows, while a negative velocity indicates a flow towards the disc’s midplane.
