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…
The formation of the Martian moons
Pascal Rosenblatt, Ryuki Hyodo, Francesco C. Pignatale +5
Almost all the planets of our solar system have moons. Each planetary system has however unique characteristics. The Martian system has not one single big moon like the Earth, not…
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…
On the Impact Origin of Phobos and Deimos IV: Volatile Depletion
Ryuki Hyodo, Hidenori Genda, Sébastien Charnoz +2
Recent works have shown that Martian moons Phobos and Deimos may have accreted within a giant impact-generated disk whose composition is about an equal mixture of Martian material…
On the impact origin of Phobos and Deimos III: resulting composition from different impactors
Francesco C. Pignatale, Sébastien Charnoz, Pascal Rosenblatt +3
The origin of Phobos and Deimos in a giant impact generated disk is gaining larger attention. Although this scenario has been the subject of many studies, an evaluation of the chem…
Size and density sorting of dust grains in SPH simulations of protoplanetary discs
Francesco C. Pignatale, Jean-François Gonzalez, Nicolas Cuello +2
The size and density of dust grains determine their response to gas drag in protoplanetary discs. Aerodynamical (size x density) sorting is one of the proposed mechanisms to explai…
2D condensation model for the inner Solar Nebula: an enstatite-rich environment
Francesco C. Pignatale, Kurt Liffman, Sarah T. Maddison +1
Infrared observations provide the dust composition in the protoplanetary discs surface layers, but can not probe the dust chemistry in the midplane, where planet formation occurs.…
Effects of photophoresis on the dust distribution in a 3D protoplanetary disc
Nicolas Cuello, Jean-François Gonzalez, Francesco C. Pignatale
Photophoresis is a physical process based on momentum exchange between an illuminated dust particle and its gaseous environment. Its net effect in protoplanetary discs (PPD) is the…
Photophoresis in protoplanetary disks: a numerical approach
Nicolas Cuello, Francesco C. Pignatale, Jean-François Gonzalez
It is widely accepted that rocky planets form in the inner regions of protoplanetary disks (PPD) about 1 - 10 AU from the star. However, theoretical calculations show that when par…
Refractory Metal Nuggets -- Formation of the First Condensates in the Solar Nebula
Kurt Liffman, Francesco C. Pignatale, Sarah Maddison +1
As gas flowed from the solar accretion disk or solar nebula onto the proto-Sun, magnetic pressure gradients in the solar magnetosphere and the inner solar nebula provided an enviro…
The effect of the regular solution model in the condensation of protoplanetary dust
Francesco C. Pignatale, Sarah T. Maddison, Vianney Taquet +2
We utilize a chemical equilibrium code in order to study the condensation process which occurs in protoplanetary discs during the formation of the first solids. The model specifica…
