Amorphous materials are metastable solids with only short-range order at the atomic scale,
which results from local intermolecular chemical bonding. The lack of long-range order …

The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

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 …

Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

Abstract The Cologne Database for Molecular Spectroscopy, CDMS, was founded 1998 to
provide in its catalog section line lists of mostly molecular species which are or may be …

A new collection of photodissociation and photoionisation cross sections for 102 atoms and
molecules of astrochemical interest has been assembled, along with a brief review of the …

Outflows from accreting, rotating, and magnetized systems are ubiquitous. Protostellar
outflows can be observed from radio to X-ray wavelengths in the continuum and a multitude …

In 2016, unambiguous evidence for the presence of the amino acid glycine, an important
prebiotic molecule, was deduced based on in situ mass-spectral studies of the coma …

Quantum mechanical tunneling of atoms is increasingly found to play an important role in
many chemical transformations. Experimentally, atom tunneling can be indirectly detected …

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 …
