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 …

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 …

Ices regulate much of the chemistry during star formation and account for up to 80% of the
available oxygen and carbon. In this paper, we use the Spitzer c2d Legacy ice survey …

From the frontiers of research on ice dynamics in its broadest sense, this review surveys the
structures of ice, the patterns or morphologies it may assume, and the physical and chemical …

All chondrites accreted∼ 3.5 wt.% C in their matrices, the bulk of which was in a
macromolecular solvent and acid insoluble organic material (IOM). Similar material to IOM is …

We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0,
and 24 μm that were obtained during the cryogenic mission of the Spitzer Space Telescope …

Several sulphur-bearing species have already been observed in different families of comets.
However, the knowledge on the minor sulphur species is still limited. The comet's sulphur …

Since the discovery of the first extrasolar planet around a solartype star, 1 more than 900
such planets outside of our solar system have been detected by ground-and space-based …

Context. High-quality vibrational spectra of solid-phase molecules in ice mixtures and for
temperatures of astrophysical relevance are needed to interpret infrared observations …

Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase
and thought to be mostly formed on icy grains. Nevertheless, there have not been any …
