Stochastic accretion of the Earth

Year: 2022

Type: article

Abstract: N-body simulations show that the Earth might have accreted stochastically from various precursor bodies with different compositions depending on their formation temperature. This scenario fits the elemental isotope composition of the bulk Earth and suggests the presence of a radial gradient in the composition of the protoplanetary disk.
