Spatial distribution of the aromatic and aliphatic carbonaceous nano-grain features in the protoplanetary disk around HD 100546
Emilie Habart, Thomas Boutéraon, Robert Brauer +4
Carbonaceous nano-grains are present at the surface of protoplanetary disks around Herbig Ae/Be stars, where most of the central star UV energy is dissipated. Efficiently coupled t…
Dust evolution: going beyond the empirical
Nathalie Ysard
A key element when modeling dust in any astrophysical environment is a self-consistent treatment of the evolution of the dust material properties (size distribution, chemical compo…
Dust emission, extinction, and scattering in LDN 1642
Mika Juvela, Sharma Neha, Emma Mannfors +3
We study the near-infrared (NIR) scattering in LDN 1642, its correlation with the cloud structure, and the ability of dust models to simultaneously explain sub-millimetre emission,…
High-resolution, 3D radiative transfer modelling IV. AGN-powered dust heating in NGC 1068
S. Viaene, A. Nersesian, J. Fritz +18
Dust emission, an important diagnostic of star formation and ISM mass throughout the Universe, can be powered by sources unrelated to ongoing star formation. In the framework of th…
High-resolution, 3D radiative transfer modelling III. The DustPedia barred galaxies
Angelos Nersesian, Sam Verstocken, Sebastien Viaene +17
Context: Dust in late-type galaxies in the local Universe is responsible for absorbing approximately one third of the energy emitted by stars. It is often assumed that dust heating…
Dust evolution across the Horsehead Nebula
T. Schirmer, A. Abergel, L. Verstraete +4
Micro-physical processes on interstellar dust surfaces are tightly connected to dust properties (i.e. dust composition, size and shape) and play a key role in numerous phenomena in…
