SPH simulations produce a scaling relation showing giant impacts heat the core by ~3000 K on average with strong thermal stratification, allowing the core to reach an adiabatic state 290 Myr later consistent with geodynamo evidence.

A scaling relation for core heating by giant impacts and implications for dynamo onset
SPH simulations produce a scaling relation showing giant impacts heat the core by ~3000 K on average with strong thermal stratification, allowing the core to reach an adiabatic state 290 Myr later consistent with geodynamo evidence.
