Snapshots of mantle temperature and velocity fields for 55 Cancri e models with T_day = 2800 K and T_night = 1150 K. High velocities (more than three times the mean mantle velocity) are indicated by red arrows. The magma ocean is indicated in red (fully molten) and orange (partially molten). H₀, H_E, and H_h indicate no internal heating, Earth-like internal heating, and high internal heating respectively. The left column shows the models with a constant CMB temperature. The right column shows the models where the CMB temperature decreases due to core cooling. For all models, a magma ocean forms on the dayside, and the nightside is partially molten. The most prominent feature is the strong upwelling that is present on the dayside.
