Planets form and obtain their compositions in disks of gas and dust around young stars. The
chemical compositions of these planet-forming disks regulate all aspects of planetary …

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. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

The composition of giant planets is imprinted by their migration history and the
compositional structure of their hosting disks. Studies in recent literature have investigated …

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 …

Cometary comae are generally depleted in nitrogen. The main carriers for volatile nitrogen
in comets are NH3 and HCN. It is known that ammonia readily combines with many acids …

Giant planets can interact with multiple and chemically diverse environments in
protoplanetary disks while they form and migrate to their final orbits. The way this interaction …

Abstract In 2017, 1I/'Oumuamua was identified as the first known interstellar object in the
Solar System. Although typical cometary activity tracers were not detected,,,–,'Oumuamua …

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 …
