Event details

The recent approach of comet 67P/Churyumov-Gerasimenko by the European Space Agency spacecraft Rosetta has revealed unexpected geomorphologic features at its surface resembling aeolian ripples or dunes, especially in the ‘neck’ region. We shall first review the physical mechanisms responsible for aeolian processes as we observe them on Earth and Mars. They provide scaling laws for the wavelength of bedforms that emerge from instability of a flat bed. This analysis at hand, we can provide an interpretation of those on comet 67P. Chair: Jo Nield
