Snapshots of mantle temperature of 55 Cancri e at different time steps for models with different surface temperature contrasts. The magma ocean is indicated in red (fully molten) and orange (partially molten). If the nightside temperature remains low enough for the surface not to be fully molten, a strong upwelling occurs preferentially on the dayside (A,B). If the nightside is fully molten, upwellings form at different locations around the CMB, and some will also move towards the nightside (C).
