The cross-disciplinary field of astrochemistry exists to understand the formation, destruction,
and survival of molecules in astrophysical environments. Molecules in space are …

Ice mantles play a crucial role in sha** the astrochemical inventory of molecules during
star and planet formation. Small-scale molecular processes have a profound impact on large …

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 …

In molecular clouds at temperatures as low as 10 K, all species except hydrogen and helium
should be locked in the heterogeneous ice on dust grain surfaces. Nevertheless …

Recent interferometer observations have found that the D 2 O/HDO abundance ratio is
higher than that of HDO/H 2 O by about one order of magnitude in the vicinity of low-mass …

Methyl mercaptan (CH 3 SH) is one of the S-bearing organic compounds found in the
interstellar medium (ISM). In this study, we investigated the surface reactions of solid CH 3 …

OH radicals play a key role as an intermediate in the water formation chemistry of the
interstellar medium. For example, the reaction of OH radicals with H2 molecules is among …

The final step of the water formation network on interstellar grain surfaces starting from the
H+ O2 route is the reaction between H and H2O2. This reaction is known to have a high …

Context. Detection of molecular oxygen and prediction of its abundance have long been a
challenge for astronomers. The low abundances observed in few interstellar sources are …

Carbonyl sulfide (OCS) is an abundant sulfur (S)-bearing species in the interstellar medium.
It is present not only in the gas phase, but also on interstellar grains as a solid; therefore …
