The thermal emission of Saturn's icy moons. Effects of topography and regolith properties

Lucas, A.; Ferrari, C.; Jacquemoud, S.

Context. The effects of space weathering and other alteration processes on the upper surface of Saturn's icy moons are yet to be explored.
Aims: We present a thermophysical model parametrised by way of regolith properties such as porosity, grain size, and composition, as well as the local topography. The modelled surface temperature and appar…
