The history of H3+ is a succession of inspiring discoveries, grueling hard work, big surprises,
and many puzzles and mistakes with their unexpected resolutions. It is a showcase …

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 …

One-dimensional aeronomical calculations of the atmospheric structure of extra-solar giant
planets in orbits with semi-major axes from 0.01 to 0.1 AU show that the thermospheres are …

We explore atmospheric escape from close-in exoplanets with the highest mass-loss rates.
First, we locate the transition from stellar X-ray and UV-driven escape to rapid Roche lobe …

Chemistry plays an important role in the interstellar medium (ISM), regulating the heating
and cooling of the gas and determining abundances of molecular species that trace gas …

The internal energy available in vibrationally excited H 2 molecules can be used to
overcome or diminish the activation barrier of various chemical reactions of interest for …

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

Aims. We investigated the chemistry of nitrogen-containing species, principally
isotopologues of CN, HCN, and HNC, in a sample of pre-protostellar cores. Methods. We …

Jupiter's upper atmosphere forms the boundary between the lower atmosphere and
interplanetary space. As the topmost layer of the atmosphere, the thermosphere absorbs …

While the physical chemistry of gas-phase ions has its roots in traditional mass spectrometry,
the growth of the field during the past two decades can be attributed to the development and …
