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 …

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 typically dark surface of the dwarf planet Ceres is punctuated by areas of much higher
albedo, most prominently in the Occator crater. These small bright areas have been …

INTRODUCTION Comets and asteroids preserve information on the earliest stages of Solar
System formation and on the composition of its building blocks. The nature of their solid …

ABSTRACT Our modern day Solar System has 4.6× 109 yr of evolution behind it with just a
few relics of its birth conditions remaining. Comets are thought to be some of the most …

The composition of the neutral gas comas of most comets is dominated by H2O, CO and
CO2, typically comprising as much as 95 per cent of the total gas density. In addition …

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 …

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 …

Abstract The VIRTIS (Visible, Infrared and Thermal Imaging Spectrometer) instrument
aboard the Rosetta spacecraft has performed extensive spectral mapping of the surface of …

The primordial disc of small icy planetesimals, once located at 15–from the Sun, was
disrupted by giant planet migration in the early Solar system. The primordial disc thereby …
