Temporal evolution of the radial distribution of the temperature in the interior of Ceres. Top row: fast accretion with t₀ = 1 Ma and t_ac = 2 Ma. Bottom row: slow accretion with t₀ = 1 Ma and t_ac = 50 Ma. Left column: Model CIa. Right column: Model CIb. Parallel to the porosity loss, the body shrinks to the final radius of 456 km. Relatively low activation energies of the minerals (Table 1) enable compaction at temperatures of mostly below 500 K. Thus, a substantial fraction of the interior consolidates before the hydrated minerals start to dehydrate.
