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…
Constraints on cometary surface evolution derived from a statistical analysis of 67P's topography
J. -B. Vincent, S. F. Hviid, S. Mottola +51
We present a statistical analysis of the distribution of large scale topographic features on comet 67P/Churyumov-Gerasimenko. We observe that the cumulative cliff height distributi…
Seasonal Mass Transfer on the Nucleus of Comet 67P/Chuyumov-Gerasimenko
H. U. Keller, S. Mottola, S. F. Hviid +47
We collect observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko. The obliquity of the rotation axis of 67P causes stro…
