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…

Modeling of the outburst on July 29th, 2015 observed with OSIRIS cameras in the southern hemisphere of comet 67P/Churyumov-Gerasimenko

A. Gicquel, M. Rose, J. -B. Vincent +60

Images of the nucleus and the coma (gas and dust) of comet 67P/Churyumov- Gerasimenko have been acquired by the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System)…

astro-ph.EP2015

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…

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…

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.…

Sublimation of icy aggregates in the coma of comet 67P/Churyumov-Gerasimenko detected with the OSIRIS cameras onboard Rosetta

A. Gicquel, J. -B. Vincent, J. Agarwal +58

Beginning in March 2014, the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) cameras began capturing images of the nucleus and coma (gas and dust) of comet 67P/…
