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 …

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. 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 …

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 …

During its 2 yr mission around comet 67P/Churyumov–Gerasimenko, ESA's Rosetta
spacecraft had the unique opportunity to follow closely a comet in the most active part of its …

The international Rosetta mission was launched in 2004 and consists of the orbiter
spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet …

Outbursts occur commonly on comets with different frequencies and scales,. Despite
multiple observations suggesting various triggering processes,, the driving mechanism of …

The Rosetta spacecraft spent~ 2 years orbiting comet 67P/Churyumov-Gerasimenko, most
of it at distances that allowed surface characterization and monitoring at submeter scales …

Infrared observations of the coma of 67P/Churyumov–Gerasimenko were carried out from
2015 July to September, ie around perihelion (2015 August 13), with the high-resolution …

Context. Since the orbital insertion of the Rosetta spacecraft, comet 67P/Churyumov-
Gerasimenko (67P) has been mapped by OSIRIS camera and VIRTIS spectro-imager …
