Quantifying the Effects of Nickel on Earth’s Inner‐Core Nucleation

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The formation of Earth’s solid inner core marks a major transition in the thermal and chemical evolution of the deep Earth, yet its origin remains paradoxical, as initial nucleation appears to require unrealistically large undercooling in the outer core.
