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

The motivation to study experimentally CO ice under mimicked interstellar conditions is
supported by the large CO gas abundances and ubiquitous presence of CO in icy grain …

In astrochemistry, complex organic molecules (COMs) are defined as species with at least
one C atom and six or more atoms in total. More than 70 COMs were detected toward …

The overabundance of gas molecules in the coldest regions of space points to a nonthermal
desorption process. Laboratory simulations show the efficient desorption of CO ice that is …

The presence of methanol among the common ice components in interstellar clouds and
protostellar envelopes has been confirmed by the James Webb Space Telescope (McClure …

At the low temperatures found in the interior of dense clouds and circumstellar regions,
along with H2O and smaller amounts of species such as CO, CO2 or CH3OH, the infrared …

This study investigates the translational and rovibrational energy of vacuum-ultraviolet
(VUV) photodesorbed CO molecules from a CO polycrystalline ice (15 K) at∼ 8 eV. The …

High-resolution observations show that typically both the dust and the gas in nearby
extended protoplanetary disks are structured, possibly related to radial and azimuthal …

Context. Interstellar surface chemistry is a complex process that occurs in icy layers that
have accumulated onto grains of different sizes. The efficiency of the surface processes …

Hexamethylentetramine has drawn a lot of attention due to its potential to produce prebiotic
species. This work aims to gain a better understanding in the chemical processes …
