The evolution of star-forming regions and their thermal balance are strongly influenced by
their chemical composition, which, in turn, is determined by the physicochemical processes …

Recent laboratory measurements have confirmed that chemical desorption (desorption of
products due to exothermic surface reactions) can be an efficient process. The impact of …

Conditions in the protosolar nebula have left their mark in the composition of cometary
volatiles, thought to be some of the most pristine material in the solar system. Cometary …

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 …

Abstract The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument
onboard the Rosetta spacecraft has measured molecular oxygen (O 2) in the coma of comet …

The desorption characteristics of molecules on interstellar dust grains are important for
modelling the behaviour of molecules in icy mantles and, critically, in describing the solid …

During the formation of stars, the accretion of surrounding material toward the central object
is thought to undergo strong luminosity outbursts followed by long periods of relative …

Extremely large deuteration of several molecules has been observed toward prestellar cores
and low-mass protostars for a decade. New observations performed toward low-mass …

Context. The behaviour of molecules in space is to a large extent governed by where they
freeze out or sublimate. The molecular binding energy is therefore an important parameter …

Complex organic molecules (COM) such as aldehydes, ketones, carboxylic acids, esters,
and amides are ubiquitous in the interstellar medium, but traditional gas phase …
