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 …

It was in 'The Magellanic Cloud'(1955)–a science fiction novel by Stanislaw Lem–that
engineers travelling to another star noticed that their spacecraft for unknown reasons …

Here we introduce the interstellar dust modelling framework THEMIS (The Heterogeneous
dust Evolution Model for Interstellar Solids), which takes a global view of dust and its …

Context. The evolution of amorphous hydrocarbon materials, aC (: H), principally resulting
from ultraviolet (UV) photon absorption-induced processing, are likely at the heart of the …

Context. Mid-infrared observations of photodissociation regions (PDRs) are dominated by
strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs are …

The surface mineralogy of dwarf planet Ceres appears to be dominated by products of rock–
fluid interactions, such as phyllosilicates—some of which are NH4-bearing—and …

We suggest that the carrier of the unidentified infrared emission (UIE) bands is an
amorphous carbonaceous solid with mixed aromatic/aliphatic structures, rather than free …

A family of unidentified infrared emission (UIE) bands has been observed throughout the
Universe. The current observed spectral properties of the UIE bands are summarized. These …

Context. The properties of hydrogenated amorphous carbon (aC: H) dust are known to
evolve in response to the local conditions. Aims. We present an adaptable model for the …

A large fraction of interstellar carbon is locked up in solid grains. The nature, origin and
evolution of these grains have been investigated for decades. A combination of …
