Planets form in disks of gas and dust around young stars. The disk molecular reservoirs and
their chemical evolution affect all aspects of planet formation, from the coagulation of dust …

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 …

We describe the 2017 release of the spectral synthesis code CLOUDY, summarizing the
many improvements to the scope and accuracy of the physics which have been made since …

Planets form and obtain their compositions in disks of gas and dust around young stars. The
chemical compositions of these planet-forming disks regulate all aspects of planetary …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

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 …

We report the detection, for the first time in space, of a new non-functionalised hydrocarbon
cycle in the direction of TMC-1: oC 6 H 4 (ortho-benzyne). We derive a column density for …

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 …

Most low-mass stars form in stellar clusters that also contain massive stars, which are
sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiation …
