Star-forming regions show a rich and varied chemistry, including the presence of complex
organic molecules—in both the cold gas distributed on large scales and the hot regions …

In situ research of cometary chemistry began when measurements from the Giotto mission at
Comet 1P/Halley revealed the presence of complex organics in the coma. New telescopes …

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 …

Context. The inner regions of the envelopes surrounding young protostars are characterized
by a complex chemistry, with prebiotic molecules present on the scales where …

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 …

Context. One of the important questions of astrochemistry is how complex organic
molecules, including potential prebiotic species, are formed in the envelopes around …

While astrochemical models are successful in reproducing many of the observed interstellar
species, they have been struggling to explain the observed abundances of complex organic …

Context. Deuteration is a powerful tracer of the history of the cold prestellar phase in star-
forming regions. Apart from methanol, little is known about deuterium fractionation of …

The high abundances of Complex Organic Molecules (COMs) with respect to methanol, the
most abundant COM, detected toward low-mass protostars, tend to be underpredicted by …
