Abstract
The Visible InfraRed and Thermal Imaging Spectrometer VIRTIS [1] instrument onboard Rosetta (ESA) has been intensively used to map the nucleus spectral and thermal properties of the nucleus comet 67/P-CG [2][3]. Here we report the thermal analysis of surfaces using thermal modeling dedicated to the comet. We focus on variations of thermo-physical properties with time, as long as the comet reaches its perihelion, and on thermal properties of the southern regions that were not illuminated during the last years due to the high obliquity of CG [4].
