Methane clathrates in the Solar System
Olivier Mousis, Eric Chassefière, Nils G. Holm +8
We review the reservoirs of methane clathrates that may exist in the different bodies of the Solar System. Methane was formed in the interstellar medium prior to having been embedd…
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…
Realistic uncertainties on Hapke model parameters from photometric measurement
Frederic Schmidt, Jennifer Fernando
Hapke proposed a convenient and widely used analytical model to describe the spectro-photometry of granular materials. Using a compilation of the published data, Hapke (2012, Icaru…
Outgassing History and Escape of the Martian Atmosphere and Water Inventory
H. Lammer, E. Chassefière, Ö. Karatekin +11
The evolution and escape of the martian atmosphere and the planet's water inventory can be separated into an early and late evolutionary epoch. The first epoch started from the pla…
Radiative transfer model for contaminated rough slabs
François Andrieu, Sylvain Douté, Frédéric Schmidt +1
We present a semi-analytical model to simulate bidirectional reflectance distribution function (BRDF) spectra of a rough slab layer containing impurities. This model has been optim…
