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 …

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 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 …

A new, more comprehensive model of gas–grain chemistry in hot molecular cores is
presented, in which nondiffusive reaction processes on dust-grain surfaces and in ice …

Abstract The Disk Substructures at High Angular Resolution Project (DSHARP) used ALMA
to map the 1.25 mm continuum of protoplanetary disks at a spatial resolution of∼ 5 au. We …

Freeze-out of the gas-phase elements onto cold grains in dense interstellar and
circumstellar media builds up ice mantles consisting of molecules that are mostly formed in …

The interstellar medium is characterized by a rich and diverse chemistry. Many of its
complex organic molecules are proposed to form through radical chemistry in icy grain …

Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …

The origin of complex organic molecules (COMs) in young Class 0 protostars has been one
of the major questions in astrochemistry and star formation. While COMs are thought to form …
