Meteorite petrology versus genetics: Toward a unified binominal classification
Emmanuel Jacquet
The current meteorite taxonomy, a result of two centuries of meteorite research and tradition, entangles textural and genetic terms in a less than consistent fashion, with some tax…
Collisions and compositional variability in chondrule-forming events
Emmanuel Jacquet
Compound chondrules, i.e. chondrules fused together, make a powerful probe of the density and compositional diversity in chondrule-forming environments, but their abundance among t…
Origin of isolated olivine grains in carbonaceous chondrites
Emmanuel Jacquet, Maxime Piralla, Pauline Kersaho +1
We report microscopic, cathodoluminescence, chemical and O isotopic measurements of FeO-poor isolated olivine grains (IOG) in the carbonaceous chondrites Allende (CV3), Northwest A…
Fingerprints of the protosolar cloud collapse in the Solar System II: Nucleosynthetic anomalies in meteorites
Emmanuel Jacquet, Francesco C. Pignatale, Marc Chaussidon +1
The isotopic heterogeneity of the Solar System shown by meteorite analyses is more pronounced for its earliest objects, the Calcium-Aluminum-rich Inclusions (CAIs). This suggests t…
Fingerprints of the protosolar cloud collapse in the Solar System I: Distribution of presolar short-lived Al
Francesco C. Pignatale, Emmanuel Jacquet, Marc Chaussidon +1
The short-lived radionuclide Al is widely used to determine the relative ages of chondrite components and timescales of physical and thermal events that attended the formati…
On beryllium-10 production in gaseous protoplanetary disks and implications on the astrophysical setting of refractory inclusions
Emmanuel Jacquet
Calcium-Aluminum-rich Inclusions (CAIs), the oldest known solids of the solar system, show evidence for the past presence of short-lived radionuclide beryllium-10, which was likely…
