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 physical properties of cometary nuclei observed today relate to their complex history
and help to constrain their formation and evolution. In this article, we review some of the …

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 …

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 …

Ammonium hydrosulphide has long since been postulated to exist at least in certain layers
of the giant planets. Its radiation products may be the reason for the red colour seen on …

Abstract 1I/'Oumuamua is the first confirmed interstellar body in our solar system. Here we
report on observations of'Oumuamua made with the Spitzer Space Telescope on 2017 …

In-situ study of comet 1P/Halley during its 1986 apparition revealed a surprising abundance
of organic coma species. It remained unclear, whether or not these species originated from …

We present the analysis of≈ 100 molecular maps of the coma of comet 67P/Churyumov-
Gerasimenko that were obtained with the MIRO submillimeter radiotelescope on board the …

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 …
