Presolar stardust in asteroid Ryugu

Jens Barosch, Larry R. Nittler, Jianhua Wang +121

We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…

A 4565 Myr old andesite from an extinct chondritic protoplanet

Jean-Alix Barrat, Marc Chaussidon, Akira Yamaguchi +5

The age of iron meteorites implies that accretion of protoplanets began during the first millions of years of the solar system. Due to the heat generated by 26Al decay, many early…

Forming pressure-traps at the snow-line to isolate isotopic reservoirs in the absence of a planet

Sébastien Charnoz, Guillaume Avice, Ryuki Hyodo +2

Pressure maxima are regions in protoplanetary disks where pebbles can be trapped because of the local absence of pressure gradient. These regions could be ideal places to form plan…

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…

Making the Planetary Material Diversity During the Early Assembling of the Solar System

Francesco C. Pignatale, Sébastien Charnoz, Marc Chaussidon +1

Chondritic meteorites, the building blocks of terrestrial planets, are made of an out-of-equilibrium assemblage of solids formed at high and low temperatures, either in our Solar s…
