The Nysa family as the main source of unequilibrated LL ordinary chondrites
M. Marsset, P. Vernazza, M. Brož +16
Context. The origin of the petrologic diversity observed in ordinary chondrites (OCs), the most common meteorites on Earth, remains debated. Competing models invoke either depth-de…
Conditions for accretion favoring an unmelted Callisto and a differentiated Ganymede
Yannis Bennacer, Olivier Mousis, Marc Monnereau +2
Analysis of Callisto's moments of inertia, derived from Galileo's gravity data, suggests that its structure is not fully differentiated. This possibly undifferentiated state contra…
Time scales of small body differentiation
Marc Monnereau, Jérémy Guignard, Adrien Néri +2
The petrologic and geochemical diversity of meteorites is a function of the bulk composition of their parent bodies, but also the result of how and when internal differentiation to…
Impact of radiogenic heating on the formation conditions of comet 67P/Churyumov-Gerasimenko
O. Mousis, A. Drouard, P. Vernazza +19
Because of the high fraction of refractory material present in comets, the heat produced by the radiogenic decay of elements such as aluminium and iron can be high enough to induce…
