We here study the transfer process of material from one hemisphere to the other (deposition
of airfall material) on an active comet nucleus, specifically 67P/Churyumov–Gerasimenko …

ABSTRACT Between 2014 December 31 and 2015 March 17, the OSIRIS cameras on
Rosetta documented the growth of a wide and deep depression in the Hapi region on Comet …

We here study the level of albedo variegation on the nucleus of Comet 67P/Churyumov–
Gerasimenko. This is done by fitting the parameters of a standard photometric phase …

Aims. We provide a measurement of the seasonal evolution of the dust deposit erosion and
accretion in the Hapi region of comet 67P/Churyumov-Gerasimenko with a vertical accuracy …

We study the size frequency distribution of the blocks located in the deeply fractured,
geologically active Enceladus South Polar Terrain with the aim to suggest their formative …

Context. One of the primary goals of the European Space Agency's Rosetta mission to comet
67P/Churyumov-Gerasimenko was to investigate the mechanisms responsible for cometary …

Aims. The Rosetta mission provided us with detailed data of the surface of the nucleus of
comet 67P/Churyumov-Gerasimenko. In order to better understand the physical processes …

Aims. We provide a detailed quantitative analysis of isolated boulder fields situated in three
different regions of comet 67P/Churyumov-Gerasimenko: Imhotep, Hapi, and Hatmehit. This …

Comet 8P/Tuttle has been selected as a possible backup target for the Comet Interceptor
mission (ESA). This comet was observed intensively during its previous perihelion passage …

When viewed from Earth, most of what we observe of a comet is dust. The influence of solar
radiation pressure on the trajectories of dust particles depends on their cross-section to …
