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 …

Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

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

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 …

Complex organic molecules have been observed for decades in the interstellar medium.
Some of them might be considered as small bricks of the macromolecules at the base of …

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 …

Glycolaldehyde (HCOCH 2 OH) is the simplest sugar and an important intermediate in the
path toward forming more complex biologically relevant molecules. In this Letter we present …

Our main knowledge about astrophysical environments relies on radiative spectra.
Absorption studies require background sources that are located hapharzadly in …
