Non-equilibrium condensation of the first Solar System solids
Sebastien Charnoz, Jérome Aleon, Marc Chaussidon +3
Primitive meteorites (chondrites) consist of an out-of-equilibrium assemblage of minerals formed during the assembling of our Solar Nebula. The conditions under which their precurs…
Perihelion history and atmospheric survival as primary drivers of the Earth`s meteorite record
Patrick M. Shober, Hadrien A. R. Devillepoix, Jeremie Vaubaillon +7
Models predict that more than half of all impacting meteoroids should be carbonaceous, reflecting the abundance of carbon-rich asteroids in the main belt and near-Earth space. Yet…
The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites
Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88
The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…
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…
Martian meteorites reflectance and implications for rover missions
Lucia Mandon, Pierre Beck, Cathy Quantin-Nataf +7
In the next decade, two rovers will characterize in situ the mineralogy of rocks on Mars, using for the first time near-infrared reflectance spectrometers: SuperCam onboard the Mar…
Noncommutative geometry, the Lorentzian Standard Model and its B-L extension
Fabien Besnard, Christian Brouder
We explore the 1-loop renormalization group flow of two models coming from a generalization of the Connes-Lott version of Noncommutative Geometry in Lorentzian signature: the Nonco…
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…
The fate of planetary cores in giant and ice-giant planets
S. Mazevet, R. Musella, F. Guyot
We used {\sl \textup{ab initio}} molecular dynamics simulations to calculate the high-pressure melting temperatures of the three potential core components. The planetary adiabats w…
Triplet excitations in the frustrated spin ladder LiCuO(SO)
Ornella Vaccarelli, Andreas Honecker, Paola Giura +4
Magnetic excitations of the recently discovered frustrated spin-1/2 two-leg ladder system LiCuO(SO) are investigated using inelastic neutron scattering, magnetic su…
Early Solar System irradiation quantified by linked vanadium and beryllium isotope variations in meteorites
Paolo A. Sossi, Frederic Moynier, Marc Chaussidon +3
X-ray emission in young stellar objects (YSOs) is orders of magnitude more intense than in main sequence stars1,2, suggestive of cosmic ray irradiation of surrounding accretion dis…
Chondrule Transport in Protoplanetary Disks
Aaron Z. Goldberg, James E. Owen, Emmanuel Jacquet
Chondrule formation remains one of the most elusive early Solar System events. Here, we take the novel approach of employing numerical simulations to investigate chondrule origin b…
Growth of calcium-aluminum-rich inclusions by coagulation and fragmentation in a turbulent protoplanetary disk: observations and modelisation
S. Charnoz, J. Aleon, N. Chaumard +2
Whereas it is generally accepted that calcium-aluminum-rich inclusions (CAIs) from chondritic meteorites formed in a hot environment in the solar protoplanetary disk, the condition…
Trace element geochemistry of ordinary chondrite chondrules: the type I/type II chondrule dichotomy
Emmanuel Jacquet, Olivier Alard, Matthieu Gounelle
We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for ca…
Trace element geochemistry of CR chondrite metal
Emmanuel Jacquet, Marine Paulhiac-Pison, Olivier Alard +2
We report trace element analyses by laser ablation inductively coupled plasma mass spectrometry of metal grains from 9 different CR chondrites, distinguishing grains from chondrule…
Chondrule trace element geochemistry at the mineral scale
Emmanuel Jacquet, Olivier Alard, Matthieu Gounelle
We report trace element analyses from mineral phases in chondrules from carbonaceous chondrites (Vigarano, Renazzo and Acfer 187), carried out by laser ablation inductively coupled…
Structure, composition, and location of organic matter in the enstatite chondrite Sahara 97096 (EH3)
Laurette Piani, FrançOis Robert, Olivier Beyssac +8
The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of analytical techniques. As the enstatite chon…
Instrumental Methods for Professional and Amateur Collaborations in Planetary Astronomy
O. Mousis, R. Hueso, J. -P. Beaulieu +57
Amateur contributions to professional publications have increased exponentially over the last decades in the field of Planetary Astronomy. Here we review the different domains of t…
Water transport in protoplanetary disks and the hydrogen isotopic composition of chondrites
Emmanuel Jacquet, François Robert
The D/H ratios of carbonaceous chondrites, believed to reflect that of water in the inner early solar system, are intermediate between the protosolar value and that of most comets.…
On the aerodynamic redistribution of chondrite components in protoplanetary disks
Emmanuel Jacquet, Matthieu Gounelle, Sébastien Fromang
Despite being all roughly of solar composition, primitive meteorites (chondrites) present a diversity in their chemical, isotopic and petrographic properties, and in particular a f…
A Self-Consistent Reduced Model for Dusty Magnetorotationally Unstable Discs
Emmanuel Jacquet, Steven Balbus
The interaction between settling of dust grains and magnetorotational instability (MRI) turbulence in protoplanetary disks is analyzed. We use a reduced system of coupled ordinary…
On linear dust-gas streaming instabilities in protoplanetary discs
Emmanuel Jacquet, Steven A. Balbus, Henrik N. Latter
We revisit, via a very simplified set of equations, a linear streaming instability (technically an overstability), which is present in, and potentially important for, dusty protopl…
Radiative Rayleigh-Taylor instabilities
Emmanuel Jacquet, Mark Krumholz
We perform analytic linear stability analyses of an interface separating two stratified media threaded by a radiation flux, a configuration relevant in several astrophysical contex…
Radial transport of refractory inclusions and their preservation in the dead zone
Emmanuel Jacquet, Sébastien Fromang, Matthieu Gounelle
Calcium-aluminum-rich inclusions (CAIs) are the oldest solar system solids known in primitive meteorites (chondrites). They predate the other components by 1-2 Myr, and likely cond…
