Structures in the protoplanetary disk of HD142527 seen in polarized scattered light
Henning Avenhaus, Sascha P. Quanz, Hans Martin Schmid +4
We present H- and Ks-band polarized differential images (PDI) of the Herbig Ae/Be star HD142527, revealing its optically thick outer disk and the nearly empty gap. The very small i…
Small vs large dust grains in transitional disks: do different cavity sizes indicate a planet?
Antonio Garufi, Sascha P Quanz, Henning Avenhaus +7
Transitional disks represent a short stage of the evolution of circumstellar material. Studies of dust grains in these objects can provide pivotal information on the mechanisms of…
Can a planet explain different cavity sizes for small and large dust grains in transition disks?
Antonio Garufi, Henning Avenhaus, Sascha Patrick Quanz
Dissimilarities in the spatial distribution of small (micron-size) and large (millimeter-size) dust grains at the cavity edge of transition disks have been recently pointed out and…
Gaps in the HD169142 protoplanetary disk revealed by polarimetric imaging: Signs of ongoing planet formation?
Sascha P. Quanz, Henning Avenhaus, Esther Buenzli +3
We present H-band VLT/NACO polarized light images of the Herbig Ae/Be star HD169142 probing its protoplanetary disk as close as ~0.1" to the star. Our images trace the face-on disk…
