The evolution of the central temperature (left panel) and the radial temperature distribution at the instance of the maximum temperature (right panel) in a body that accreted instantaneously to D = 35 km at t₀ = 1.6 Ma. Consideration of both the heat transport by melt and the redistribution of radioactive elements (solid line), consideration of the heat transport by melt and neglection of the redistribution of radioactive elements (dashed line), consideration of the redistribution of radioactive elements and neglection of the heat transport by melt (dot-dashed line), neglection of both the heat transport by melt and the redistribution of radioactive elements (dotted line).
