Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows
requires answering the following questions: Is the flow strong enough to initiate sediment …

This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

Comets are considered to be some of the most pristine and unprocessed Solar system
objects accessible to in situ exploration. Investigating their molecular and elemental …

We analyzed more than 200 OSIRIS NAC images with a pixel scale of 0.9− 2.4 m/pixel of
comet 67P/Churyumov-Gerasimenko (67P) that have been acquired from onboard the …

We report on laboratory experiments to shed light on dust charging and transport that have
been suggested to explain a variety of unusual phenomena on the surfaces of airless …

ABSTRACT The Rosetta probe, orbiting Jupiter-family comet 67P/Churyumov–
Gerasimenko, has been detecting individual dust particles of mass larger than 10− 10 kg by …

Context. We investigate the formation and evolution of comet nuclei and other trans-
Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet …

Several sulphur-bearing species have already been observed in different families of comets.
However, the knowledge on the minor sulphur species is still limited. The comet's sulphur …

Context. The complex shape of comet 67P and its oblique rotation axis cause pronounced
seasonal effects. Irradiation and hence activity vary strongly. Aims. We investigate the …

We collect observational evidence that supports the scheme of mass transfer on the nucleus
of comet 67P/Churyumov–Gerasimenko. The obliquity of the rotation axis of 67P causes …
