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 …

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 …

Isotope abundance ratios have an important role in astronomy and planetary sciences,
providing insights into the origin and evolution of the Solar System, interstellar chemistry and …

To date, about two dozen low-mass embedded protostars exhibit rich spectra with lines of
complex organic molecules (COMs). These protostars seem to possess a different …

Context. Complex organic molecules are detected in many sources in the warm inner
regions of envelopes surrounding deeply embedded protostars. Exactly how these species …

ABSTRACT Our modern day Solar System has 4.6× 109 yr of evolution behind it with just a
few relics of its birth conditions remaining. Comets are thought to be some of the most …

Quantifying the composition of the material in protoplanetary disks is essential to
determining the potential for exoplanetary systems to produce and support habitable …

The complex organic molecules (COMs) detected in star-forming regions are the precursors
of the prebiotic molecules that can lead to the emergence of life. By studying COMs in more …

A quarter century after the detection of the last interstellar carboxylic acid, acetic acid (CH 3
COOH), we report the discovery of a new one, the cis-trans form of carbonic acid …
