Vapor-Melt Exchange -- Constraints on Chondrite Formation Conditions and Processes
Denton S. Ebel, Conel M. O'D. Alexander, Guy Libourel
The bulk volatile contents of chondritic meteorites provide clues to their origins. Matrix and chondrules carry differing abundances of moderately volatile elements, with chondrule…
Experimental phase function and degree of linear polarization curve of olivine and spinel and the origin of the Barbarian polarization behavior
E. Frattin, J. Martikainen, O. Muñoz +7
We explore experimentally possible explanations of the polarization curves of the sunlight reflected by the Barbarian asteroids. Their peculiar polarization curves are characterize…
Subsolar Al/Si and Mg/Si ratios of non-carbonaceous chondrites reveal planetesimal formation during early condensation in the protoplanetary disk
A. Morbidelli, G. Libourel, H. Palme +2
The Al/Si and Mg/Si ratios in non-carbonaceous chondrites are lower than the solar (i.e., CI-chondritic) values, in sharp contrast to the non-CI carbonaceous meteorites and the Ear…
Asteroid Ryugu Before the Hayabusa2 Encounter
Koji Wada, Matthias Grott, Patrick Michel +31
Asteroid (162173) Ryugu is the target object of Hayabusa2, an asteroid exploration and sample return mission led by Japan Aerospace Exploration Agency (JAXA). Ground-based observat…
Magmatic sulfides in the porphyritic chondrules of EH enstatite chondrites
Laurette Piani, Yves Marrocchi, Guy Libourel +1
The nature and distribution of sulfides within 17 porphyritic chondrules of the Sahara 97096 EH3 enstatite chondrite have been studied by backscattered electron microscopy and elec…
Rapid temperature changes and the early activity on comet 67P/Churyumov-Gerasimenko
V. Alí-Lagoa, M. Delbo', G. Libourel
The so-called "early activity" of comet 67P/Churyumov-Gerasimenko has been observed to originate mostly in parts of the concave region or "neck" between its two lobes. Since activi…
