A coupled thermal-accretion model finds that Callisto can stay unmelted while Ganymede fully differentiates if both formed over more than 2 million years starting more than 3.5 million years after CAIs, even with up to 30% of mass from km-scale impactors.

Conditions for accretion favoring an unmelted Callisto and a differentiated Ganymede
A coupled thermal-accretion model finds that Callisto can stay unmelted while Ganymede fully differentiates if both formed over more than 2 million years starting more than 3.5 million years after CAIs, even with up to 30% of mass from km-scale impactors.
