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…
Tidal pull of the Earth strips the proto-Moon of its volatiles
S. Charnoz, P. A. Sossi, Y-N Lee +7
Prevailing models for the formation of the Moon invoke a giant impact between a planetary embryo and the proto-Earth \citep{Canup_2004, Cuk_Stewart_2012}. Despite similarities in t…
Spatially resolving the chemical composition of the planet building blocks
A. Matter, F. Pignatale, B. Lopez
The inner regions of protoplanetary discs (from 0.1 to 10 au) are the expected birthplace of planets, especially telluric. In those high temperature regions, solids can expe…
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…
Size and density sorting of dust grains in SPH simulations of protoplanetary disc II: Fragmentation
Francesco C. Pignatale, Jean-François Gonzalez, Bernard Bourdon +1
Grain growth and fragmentation are important processes in building up large dust aggregates in protoplanetary discs. Using a 3D two-phase (gas-dust) SPH code, we investigate the co…
