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 …

Sulfur is the tenth most abundant element in the universe and is known to play a significant
role in biological systems. Accordingly, in recent years there has been increased interest in …

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 …

Context. Many molecules observed in the interstellar medium are thought to result from the
thermal desorption of ices. Parameters such as the desorption energy and pre-exponential …

Laboratory experiments provide a valuable complement to explore the fundamental physics
of space plasmas without the limitations inherent to spacecraft measurements. Specifically …

Abstract The Jupiter Trojan asteroids are a key population for understanding the chemical
and dynamical evolution of the Solar System. Surface compositions of Trojans, in turn …

The ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instrument aboard
the Rosetta mission revolutionized our understanding of cometary material composition …

We present the first ultraviolet spectra of Jupiter Trojans. These observations were carried
out using the Space Telescope Imaging Spectrograph on the Hubble Space Telescope and …

The chemistry of phosphorus in star-and planet-forming regions is poorly understood,
despite the central role of phosphorus in terrestrial biochemistry. We present Atacama Large …

Abstract Carbon, hydrogen, nitrogen, oxygen, and sulfur are the main elements involved in
the solid-phase chemistry of various astrophysical environments. Among these elements …
