Figure 5: Comparison of N distribution in non-atmosphere reservoirs of planetary embryos that grew either via instantaneous or collisional accretion.

Figure 5:

Planetary embryos that grew via instantaneous accretion and then underwent differentiation have a much higher percentage of initially accreted N in their (a) magma oceans and (b) cores relative to planetary embryos that grew via collisional accretion of differentiated planetesimals. In this figure, Vesta-sized differentiated bodies (0.04 R⊕) are assumed to be the seeds of collisional accretion leading to Moon- and Mars-sized planetary embryos.
