The spatial extent of Polycyclic Aromatic Hydrocarbons emission in the Herbig star HD 179218
Anas S. Taha, Lucas Labadie, Eric Pantin +7
We investigate in the mid-IR the spatial properties of the PAHs emission in the disk of HD179218. We obtained mid-IR images in the PAH1, PAH2 and Si6 filters at 8.6, 11.3 and 12.5…
On the inner disk structure of MWC480: evidence for asymmetries?
Narges Jamialahmadi, Bruno Lopez, Philippe Berio +7
Studying the physical conditions structuring the young circumstellar disks is required for understanding the onset of planet formation. Of particular interest is the protoplanetary…
Modelling of mid-infrared interferometric signature of hot exozodiacal dust emission
Florian Kirchschlager, Sebastian Wolf, Robert Brunngräber +3
Hot exozodiacal dust emission was detected in recent surveys around two dozen main sequence stars at distances of less than using H and K band interferometry. Due to…
A study of dust properties in the inner sub-au region of the Herbig Ae star HD 169142 with VLTI/PIONIER
L. Chen, A. Kospal, P. Abraham +3
An essential step to understanding protoplanetary evolution is the study of disks that contain gaps or inner holes. The pretransitional disk around the Herbig star HD 169142 exhibi…
