Freeze-out of the gas-phase elements onto cold grains in dense interstellar and
circumstellar media builds up ice mantles consisting of molecules that are mostly formed in …

In 2016, unambiguous evidence for the presence of the amino acid glycine, an important
prebiotic molecule, was deduced based on in situ mass-spectral studies of the coma …

We present an extended version of the two-phase gas–grain code nautilus to the three-
phase modelling of gas and grain chemistry of cold cores. In this model, both the mantle and …

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 …

It was in 'The Magellanic Cloud'(1955)–a science fiction novel by Stanislaw Lem–that
engineers travelling to another star noticed that their spacecraft for unknown reasons …

Reactions in interstellar ices are shown to be capable of producing key prebiotic molecules
without energetic radiation that are necessary for the origins of life. When present in …

Context. High-quality vibrational spectra of solid-phase molecules in ice mixtures and for
temperatures of astrophysical relevance are needed to interpret infrared observations …

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

Context. Complex organic species are known to be abundant toward low-and high-mass
protostars. No statistical study of these species toward a large sample of high-mass …

Context. Complex organic molecules (COMs) are thought to form on icy dust grains in the
earliest phase of star formation. The evolution of these COMs from the youngest Class 0/I …
