Dust processing in photodissociation regions - Mid-IR emission modelling
M. Compiegne, A. Abergel, L. Verstraete +1
Mid-infrared spectroscopy of dense illuminated ridges (or photodissociation regions, PDRs) suggests dust evolution. Such evolution must be reflected in the gas physical properties…
The Molecular Hydrogen Explorer H2EX
F. Boulanger, J. P. Maillard, P. Appleton +12
The Molecular Hydrogen Explorer, H2EX, was proposed in response to the ESA 2015 - 2025 Cosmic Vision Call as a medium class space mission with NASA and CSA participations. The miss…
Spatially extended PAHs in circumstellar disks around T Tauri and Herbig Ae stars
V. C. Geers, E. F. van Dishoeck, R. Visser +4
Our aim is to determine the presence and location of the emission from polycyclic aromatic hydrocarbons (PAHs) towards low and intermediate mass young stars with disks using large…
Aromatic emission from the ionised mane of the Horsehead nebula
M. Compiegne, A. Abergel, L. Verstraete +5
We study the evolution of the Aromatic Infrared Bands (AIBs) emitters across the illuminated edge of the Horsehead nebula and especially their survival and properties in the HII re…
