Full text not available from this repository. AbstractAims. 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.
Methods. We use images of the OSIRIS cameras onboard Rosetta to follow the temporal changes from 24 May 2015 to 11 July 2015.
Results. The morphological changes observed on the surface are visible in the form of roundish features, which are growing in size from a given location in a preferential direction, at a rate of 20 –29 cm h^{−1} during the observational period. The location where changes started and the contours of the expanding features are bluer than the surroundings, suggesting the presence of ices (H^_{2}O and/or CO^_{2}) exposed on the surface. No increase in dust activity is observed during the period of changes. The observed changes are best interpreted by the rapid progression of a sublimation front. | Item URL in elib: | https://elib.dlr.de/97555/ |
