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 …

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 …

Before Rosetta, the space missions Giotto and Stardust shaped our view on cometary dust,
supported by plentiful data from Earth based observations and interplanetary dust particles …

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 …

The properties of dust in the protoplanetary disk are key to understanding the formation of
planets in our Solar System. Many models of dust growth predict the development of fractal …

Solar system formation models predict that the building blocks of planetesimals were mm-to
cm-sized pebbles, aggregates of ices and non-volatile materials, consistent with the …

Context. The properties of the smallest subunits of cometary dust contain information on their
origin and clues to the formation of planetesimals and planets. Compared to interplanetary …

Abstract Comet 67P/Churyumov-Gerasimenko (67P hereinafter) is characterized by a dust
transfer from the southern hemi-nucleus to the night-side northern dust deposits, which …

We review the complex relationship between the dust-to-gas mass ratio usually estimated in
the material lost by comets, and the refractory-to-ice mass ratio inside the nucleus, which …
