Molecular hydrogen is the most abundant molecule in the universe. It is the first one to form
and survive photo-dissociation in tenuous environments. Its formation involves catalytic …

Since we intend to review experimental and theoretical studies of physicochemical
processes occurring on cosmic dust grains in very cold regions in space, we start with a brief …

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 …

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 …

Molecular absorption and emission bands dominate the visible, infrared, and submillimeter
spectra of most objects with associated gas. These observations reveal a surprisingly rich …

We survey the current situation regarding chemical modelling of the synthesis of molecules
in the interstellar medium. The present state of knowledge concerning the rate coefficients …

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 …

Context. Mantles of iced water mixed with carbon monoxyde, formaldehyde, and methanol
are formed during the so-called prestellar core phase. In addition, radicals are also thought …

Context. The synthesis of water is one necessary step in the origin and development of life. It
is believed that pristine water is formed and grows on the surface of icy dust grains in dark …

Water is abundantly present in the Universe. It is the main component of interstellar ice
mantles and a key ingredient for life. Water in space is mainly formed through surface …
