Context. Vacuum-ultraviolet (VUV) photons are important drivers of chemical processes in
space. Thus, it is important to accurately characterize and constrain photorates in different …

The environment of a comet is a fascinating and unique laboratory to study plasma
processes and the formation of structures such as shocks and discontinuities from electron …

Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the
exploration of a little-processed long-period comet, possibly entering the inner Solar System …

New high-level ab initio quartic force field (QFF) methods are explored which provide
spectroscopic data for the electronically excited states of the carbon monoxide, water, and …

Molecular oxygen, O2, is vital to life on Earth and possibly also on exoplanets. Although the
biogenic processes leading to its accumulation in Earth's atmosphere are well understood …

In interplanetary bodies, organics are found originating from various environments. We
replicate the solid-phase conditions in a laboratory to elucidate the step-by-step evolution of …

Molecular cations are present in various astronomical environments, most notably in
cometary atmospheres and tails where sunlight produces exceptionally bright near-UV to …

ABSTRACT The European Space Agency/Rosetta mission escorted comet 67P/Churyumov–
Gerasimenko and witnessed the evolution of its coma from low activity (∼ 2.5–3.8 au) to rich …

A shock wave can be formed by continuous mass loading of the solar wind by the newly
formed cometary ions. The formation of ion acoustic shocklets has thus been studied in a …

We investigate the atmospheric response to seasonal variations in sea surface temperature
(SST) in the eastern tropical Atlantic during the boreal summer, using the Weather Research …
