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 …

The interstellar medium of galaxies is the reservoir out of which stars are born and into
which stars inject newly created elements as they age. The physical properties of the …

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 …

Abstract The SILCC (SImulating the Life-Cycle of molecular Clouds) project aims to self-
consistently understand the small-scale structure of the interstellar medium (ISM) and its link …

We present a novel chemical database for gas-phase astrochemistry. Named the KInetic
Database for Astrochemistry (KIDA), this database consists of gas-phase reactions with rate …

Gas-phase processes were long thought to be the key formation mechanisms for complex
organic molecules in star-forming regions. However, recent experimental and theoretical …

Aims. Photodissociation by UV light is an important destruction mechanism for carbon
monoxide (CO) in many astrophysical environments, ranging from interstellar clouds to …

Stars form within molecular clouds but our understanding of this fundamental process
remains hampered by the complexity of the physics that drives their evolution. We review our …

▪ Abstract All neutral atomic hydrogen gas and a large fraction of the molecular gas in the
Milky Way Galaxy and external galaxies lie in PDRs, and PDRs are the origin of most of the …

▪ Abstract Recent advances in the understanding of the chemical processes that occur
during all stages of the formation of stars, from the collapse of molecular clouds to the …
