Diurnal ejection of boulder clusters on comet 67P lasting beyond 3 AU
Xian Shi, Xuanyu Hu, Jessica Agarwal +6
Ejection of large boulder-like debris is a vigorous form of cometary activity that is unlikely induced by water ice out-gassing alone but rather associated with the sublimation of…
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…
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…
Laboratory Observations and Simulations of Phase Reddening
S. E. Schröder, Y. Grynko, A. Pommerol +3
The visible reflectance spectrum of many solar system bodies changes with changing viewing geometry for reasons not fully understood. It is often observed to redden (increasing spe…
Variegation and space weathering on asteroid 21 Lutetia
S. E. Schröder, H. U. Keller, S. Mottola +4
During the flyby in 2010, the OSIRIS camera on-board Rosetta acquired hundreds of high-resolution images of asteroid Lutetia's surface through a range of narrow-band filters. While…
