A Long‐Lived Planetesimal Dynamo Powered by Core Crystallization
The existence of numerous iron meteorite groups indicates that some planetesimals underwent melting that led to metal‐silicate segregation, sometimes producing metallic cores. Meteorite paleomagnetic
The origin of s-process isotope heterogeneity in the solar protoplanetary disk
Rocky asteroids and planets display nucleosynthetic isotope variations that are attributed to the heterogeneous distribution of stardust from different stellar sources in the solar protoplanetary
Collisional mixing between inner and outer solar system planetesimals inferred from the Nedagolla iron meteorite
The ungrouped iron meteorite Nedagolla is the first meteorite with bulk Mo, Ru, and Ni isotopic compositions that are intermediate between those of the noncarbonaceous (NC) and carbonaceous (CC)
Isotopic Evolution of the Inner Solar System Inferred from Molybdenum Isotopes in Meteorites
The fundamentally different isotopic compositions of non-carbonaceous (NC) and carbonaceous (CC) meteorites reveal the presence of two distinct reservoirs in the solar protoplanetary disk that were
Interpretation and diversity of exoplanetary material orbiting white dwarfs
Nine metal-polluted white dwarfs are observed with medium-resolution optical spectroscopy, where photospheric abundances are determined and interpreted by comparison with Solar system objects. An
Complementary nucleosynthetic isotope anomalies of Mo and W in chondrules and matrix in the Allende carbonaceous chondrite: The case for hydrothermal metamorphism and its implications
The remarkable complementary isotopic relationship in the Allende chondrite between chondrules (depleted in s‐process molybdenum and tungsten) and matrix (enriched in these nuclides) has been
