The thermal, mechanical, structural, and dielectric properties of cometary nuclei after Rosetta
O. Groussin, N. Attree, Y. Brouet +16
The physical properties of cometary nuclei observed today relate to their complex history and help to constrain their formation and evolution. In this article, we review some of th…
Constraining models of activity on comet 67P/Churyumov-Gerasimenko with Rosetta trajectory, rotation, and water production measurements
Nicholas Attree, Laurent Jorda, Olivier Groussin +11
Aims. We use four observational data sets, mainly from the Rosetta mission, to constrain the activity pattern of the nucleus of comet 67P/Churyumov-Gerasimenko. Methods. We develop…
Tensile Strength of 67P/Churyumov-Gerasimenko Nucleus Material from Overhangs
N. Attree, O. Groussin, L. Jorda +52
We directly measure twenty overhanging cliffs on the surface of comet 67P/Churyumov-Gerasimenko extracted from the latest shape model and estimate the minimum tensile strengths nee…
Thermal fracturing on comets. Applications to 67P/Churyumov-Gerasimenko
N. Attree, O. Groussin, L. Jorda +12
We simulate the stresses induced by temperature changes in a putative hard layer near the surface of comet 67P/Churyumov--Gerasimenko with a thermo-viscoelastic model. Such a layer…
Surface charging of thick porous water ice layers relevant for ion sputtering experiments
A. Galli, A. Vorburger, A. Pommerol +6
We use a laboratory facility to study the sputtering properties of centimeter-thick porous water ice subjected to the bombardment of ions and electrons to better understand the for…
Circum-planetary discs as bottlenecks for gas accretion onto giant planets
Guillaume Rivier, Aurélien Crida, Alessandro Morbidelli +1
With hundreds of exoplanets detected, it is necessary to revisit giant planets accretion models to explain their mass distribution. In particular, formation of sub-jovian planets r…
