Extended Data Fig. 9. Comparison between the calculated nitrogen solubility constants (SN) from this study and the fixed values used in previous studies.

Extended Data Fig. 9.

The effective solubility constants for N vary with the size of protoplanetary bodies with variations in the range of an order of magnitude from a Vesta-sized to a Mars-sized protoplanet. Therefore, using a fixed solubility constant, as used in previous studies3,4,10 to calculate the solubilities of N in magma oceans for rocky bodies having different sizes can give erroneous results.
