Are fractured cliffs the source of cometary dust jets ? Insights from OSIRIS/Rosetta at 67P
J. -B. Vincent, N. Oklay, M. Pajola +52
Dust jets, i.e. fuzzy collimated streams of cometary material arising from the nucleus, have been observed in-situ on all comets since the Giotto mission flew by comet 1P/Halley in…
On the limiting Markov process of energy exchanges in a rarely interacting ball-piston gas
Péter Bálint, Thomas Gilbert, Péter Nándori +2
We analyse the process of energy exchanges generated by the elastic collisions between a point-particle, confined to a two-dimensional cell with convex boundaries, and a `piston',…
Temporal morphological changes in the Imhotep region of comet 67P/Churyumov-Gerasimenko
O. Groussin, H. Sierks, C. Barbieri +45
We report on the first major temporal morphological changes observed on the surface of the nucleus of comet 67P/Churyumov-Gerasimenko, in the smooth terrains of the Imhotep region.…
Gravitational slopes, geomorphology, and material strengths of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
O. Groussin, L. Jorda, A. -T. Auger +49
We study the link between gravitational slopes and the surface morphology on the nucleus of comet 67P/Churyumov-Gerasimenko and provide constraints on the mechanical properties of…
