Modeling Dust in the Interstellar Medium

, 2012
We are in a very special moment for the study of the interstellar medium (ISM). The Spitzer Space Telescope had provided, and currently Herschel Space Observatory is providing, invaluable infrared (IR) observations of a variety of astrophysical ...

Release of large polycyclic aromatic hydrocarbons and fullerenes by cosmic rays from interstellar dust

, 2019
International audienceContext. Top-down chemistry is believed to be responsible for the formation of the large molecular compounds such as the polycyclic aromatic hydrocarbon-like molecules and the fullerenes observed in the interstellar medium.

Electrostatic Transport Characteristics of Olivine Particles under Electron Irradiation in Vacuum

The Astrophysical Journal
Electrostatic dust transport on airless planetary bodies, such as the Moon, plays a crucial role in shaping their surface environment and influencing the evolution of surface materials.

The interstellar flux gap: From dust to kilometer-scale objects

Context. Three kilometer-sized interstellar objects (ISOs) have been detected transiting the Solar System, and spacecraft have directly measured micrometer-scale interstellar dust (ISD).

Lifecycle of the interstellar dust grains in our galaxy viewed with AKARI/MIR all-sky survey

, 2012
The interstellar dust grains are formed and supplied to interstellar space from asymptotic giant branch (AGB) stars or supernova remnants, and become constituents of the star- and planet-formation processes that lead to the next generation of stars. Both

A Detection of Circumgalactic Dust at Megaparsec Scales with Maximum Likelihood Estimation

The Astrophysical Journal
One of the more surprising astrophysical discoveries of the past decade has been the presence of enormous quantities of dust at megaparsec distances from galaxies, which has important implications for galaxy evolution, the circumgalactic and ...

Dust coagulation in ISM

, 1989
Coagulation is an important mechanism in the growth of interstellar and interplanetary dust particles. The microphysics of the coagulation process was theoretically analyzed as a function of the physical properties of the coagulating grains, i.e., their ...

From small dust to micron-sized aggregates: The influence of structure and composition on the dust optical properties

International audienceContext. Models of astrophysical dust are key to understanding several physical processes, from the role of dust grains as cooling agents in the interstellar medium (ISM) to their evolution in dense circumstellar discs, explaining ...
