Extended Data Fig. 8. The effects of (a) the extent of atmosphere retention after final-step of Earth’s accretion and (b) the extent of emulsification of the impactor’s core in the target’s magma ocean on N budget of the BSE.

Extended Data Fig. 8.

For scenario 10 (as defined in Fig. 5a) and 50 ppm of accreted N, it can be seen that N budget of the present-day BSE can be satisfied for ~60-100 % of atmosphere retention on Earth after its final accretion event (a) and for ~50-100 % emulsification of the impactor’s core in the target’s MO (b) during every step of accretion. Lesser extent of final-stage atmospheric retention or lesser degree of emulsification of the impactor’s core would require higher amount of accreted N (>50 ppm) in the seed planetary embryos (here Mars-sized) to satisfy the N budget of the present-day BSE.
