Surface Temperatures and Water Ice Sublimation Rate of Oxo Crater: A Comparison With Juling Crater

Raponi, A.; De Sanctis, M. C.; Formisano, M. +3 more

Dwarf planet Ceres is characterized by several sites hosting (or have hosted) ice-rich patches as revealed by the Dawn's Visible and InfraRed spectrometer. The study of the illumination conditions including the effects of the local topography become critical in the estimation of the ice lifetime as well as the water vapor production rate. In this …

Thermal Stability of Water Ice in Ceres' Craters: The Case of Juling Crater

Raponi, A.; Tosi, F.; De Sanctis, M. C. +4 more

Ice thermal stability on the surface of the dwarf planet Ceres is an important issue linked to the Herschel observations of water vapor around Ceres. One of these surficial ice deposits is located within the 20-km crater Juling (35°S, 168°E). The study of water ice exposure in this specific crater is particularly interesting because it has been ob…
