Elements with differing siderophile affinities provide insights into various stages of planetary
accretion. The isotopic anomalies they exhibit offer a deeper understanding of the materials …

Samples from asteroid Ryugu, brought back by asteroid explorer Hayabusa2, are important
for investigating the origin and evolution of the solar system. Here, we report the elemental …

The giant planets of the Solar System formed on initially compact orbits, which transitioned
to the current wider configuration by means of an orbital instability. The timing of that …

In order to understand the origin of oldhamite (CaS) in enstatite meteorites, we report Ca
isotopic compositions (δ 44/40 Ca) of oldhamite (obtained from water leachate of bulk …

Context. Rocky planets form by the concentration of solid particles in the inner few au
regions of planet-forming disks. Their chemical composition reflects the materials in the disk …

Earth's deep mantle hosts continental-scale enigmatic structures whose origin,
characteristics, and fate are uncovered by advances in tomographic modeling, geochemical …

The solidification of a deep magma ocean occurred early in Earth's history. Although the
initial amount of H 2 O in Earth's magma ocean is predicted to be low (eg,< 3000 ppm), as …

Different discretizations methods applied to models of core/mantle segregations are tested
(single stage, multistage accretion, results of N-body simulations) in order to test the …

The mineralogy of planetary mantles formed under reducing conditions, as documented in
the inner regions of the solar system, is not well constrained. We present thermodynamic …

Terrestrial planets are thought to be made of chondritic materials. However, previous studies
have suggested that the Earth's upper mantle is depleted in some incompatible refractory …
