Seismic detection of the martian core
Clues to a planet's geologic history are contained in its interior structure, particularly its core.
We detected reflections of seismic waves from the core-mantle boundary of Mars using …

Accretion of the Earth—missing components?
Primitive meteorites preserve the chemical and isotopic composition of the first aggregates

The effect of Jupiter's formation on the distribution of refractory elements and inclusions in meteorites
We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

I/Pu reveals Earth mainly accreted from volatile-poor differentiated planetesimals
The observation that mid-ocean ridge basalts had~ 3× higher iodine/plutonium ratios
(inferred from xenon isotopes) compared to ocean island basalts holds critical insights into …

Nucleosynthetic isotope anomalies of zinc in meteorites constrain the origin of Earth's volatiles
Material inherited from different nucleosynthesis sources imparts distinct isotopic signatures
to meteorites and terrestrial planets. These nucleosynthetic isotope anomalies have been …

Early volatile depletion on planetesimals inferred from C–S systematics of iron meteorite parent bodies
MM Hirschmann, EA Bergin… - Proceedings of the …, 2021 - National Acad Sciences
During the formation of terrestrial planets, volatile loss may occur through nebular
processing, planetesimal differentiation, and planetary accretion. We investigate iron …

Primitive asteroids as a major source of terrestrial volatiles
The origins of Earth's volatiles are debated. Recent studies showed that meteorites display
unique mass-independent isotopic signatures of the volatile element Zn, suggesting that …

The case for the angrite parent body as the archetypal first-generation planetesimal: Large, reduced and Mg-enriched
Angrites are silica-undersaturated achondrites formed very early in the history of the Solar
System, and the most volatile-depleted known meteorites. As such, the study of angrites can …
