Discovery of a Companion Candidate in the HD169142 Transition Disk and the Possibility of Multiple Planet Formation
Maddalena Reggiani, Sascha P. Quanz, Michael R. Meyer +14
We present L' and J-band high-contrast observations of HD169142, obtained with the VLT/NACO AGPM vector vortex coronagraph and the Gemini Planet Imager, respectively. A source loca…
Shadows and cavities in protoplanetary disks: HD163296, HD141569A, and HD150193A in polarized light
Antonio Garufi, Sascha P. Quanz, Hans Martin Schmid +3
The morphological evolution of dusty disks around young (few Myr-old) stars is pivotal to better understand planet formation. Since both dust grains and the global disk geometry ev…
HD100546 Multi-Epoch Scattered-Light Observations
Henning Avenhaus, Sascha P. Quanz, Michael R. Meyer +3
We present H, Ks and L filter polarimetric differential imaging (PDI) data for the transitional disk around HD100546 obtained in 2013, together with an improved re-reduction of pre…
Resolved images of the protoplanetary disk around HD 100546 with ALMA
Jaime E. Pineda, Sascha P. Quanz, Farzana Meru +4
The disk around the Herbig Ae/Be star HD 100546 has been extensively studied and it is one of the systems for which there are observational indications of ongoing and/or recent pla…
