In situ research of cometary chemistry began when measurements from the Giotto mission at
Comet 1P/Halley revealed the presence of complex organics in the coma. New telescopes …

This chapter reviews the estimates of the dust-to-gas and refractory-to-ice mass ratios
derived from Rosetta measurements in the lost materials and the nucleus of 67P/Churyumov …

Context. The ESA Rosetta spacecraft (S/C) is tracking comet 67P/Churyumov-Gerasimenko
in close vicinity. This prolonged encounter enables studying the evolution of the volatile …

We examine the evolution of the water production of comet 67P/Churyumov–Gerasimenko
during the Rosetta mission (2014 June–2016 May) based on in situ and remote sensing …

The processes that led to the formation of the planetary bodies in the Solar system are still
not fully understood. Using the results obtained with the comprehensive suite of instruments …

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 …

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. We present an investigation of the surface properties of areas on the nucleus of
comet 67P/Churyumov-Gerasimenko. Aims. We aim to show that transport of material from …

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 …
