| Simplified cartoon of Pluto's interior structure. | Simplified cartoon of the troughs observed at the surface of Sputnik Planitia. | Video showing the effect of a periodic variation of the surface temperature on the layer of fluid. The numerical simulation is conducted in 2D Cartesian geometry for an incompressible and isoviscous fluid. The bottom surface is adiabatic and there is no internal heating, so the only source of heat is the secular cooling caused by variations in surface temperature. |
