Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …

The physical and chemical processes leading to the formation of molecules in the interstellar
medium (ISM) sthe vast voids between the starssfascinated scientists since the first detection …

We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new
reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are …

Context. Near-to mid-infrared observations of molecular emission from protoplanetary disks
show that the inner regions are rich in small organic volatiles (eg, C 2 H 2 and HCN). Trends …

A global-mean model of coupled neutral and ion chemistry on Titan has been developed.
Unlike the previous coupled models, the model involves ambipolar diffusion and escape of …

The photochemistry of N 2 and CH 4 in the atmosphere of Titan leads to a very rich
chemistry which is not well understood. The aim of our study is to improve our understanding …

There is now ample evidence from an assortment of experiments, especially those involving
the CRESU (Cinétique de Réaction en Ecoulement Supersonique Uniforme) technique, that …

A new era in chemical kinetics was heralded 20 years ago by the results reported by
Bertrand Rowe, then at the Laboratoire d AØrothermique in Meudon.[1] Using an apparatus …

The field of astrochemistry concerns the formation and abundance of molecules in the
interstellar medium, star-forming regions, exoplanets, and solar system bodies. These …

A major aim of astrochemistry is to explain the nature and abundance of the molecules
observed in the interstellar medium (ISM). Three kinds of activity are involved:(a) the …
