Dataset for "Rapid accretion of enstatite chondrite (EH)-like embryos as impactors for the proto-Earth"

However, this differentiation remains enigmatic: their small size precludes gravity-driven permeable flow, and enstatite exhibits a high melting temperature. Here, we report high-pressure melting experiments on EH3 chondrite, coupled with three-dimensional (3D) X-ray computed tomography, showing that more than 20% of silicate partial melting can enable efficient metal segregation.

Thermodynamic simulations of EH chondrite-like embryo thermal evolution further demonstrate that heat from radioactive decay (26Al, 60Fe, 40K) allows core formation only if embryos accreted within 1.4 Myr post-CAIs. In contrast, EH chondrite parent bodies formed later (1.92–2.0 Myr post-CAIs) with radii of 110–190 km. Our findings suggest two distinct evolutionary trajectories of EH chondrite-like embryos, providing constraints on core formation in small planetary embryos and fundamental references for the formation of planets in the early solar system.This dataset contains codes and simulation results for thermal simulations of enstatite chondrite (EH) -like embryos and enstatite chondrite parent bodies.The code was written in Python
