    Hi Dr. Sokol, yes in our model we assumed that the early planetesimals underwent complete metal-silicate differentiation owing to heating by 26Al decay. This is perhaps an end-member, but the support for this comes from iron meteorites, which suggest that the earliest formed protoplanets underwent metal-silicate differentiation.

    Thanks for the great presentation.

    According to your model, nitrogen differentiation between the silicate mantle and the core was carried out already in the planetisimals. But did planetisimals have magma oceans?
