An Extreme-AO Search for Giant Planets around a White Dwarf --VLT/SPHERE performance on a faint target GD 50
S. Xu, S. Ertel, Z. Wahhaj +3
CONTEXT. Little is known about the planetary systems around single white dwarfs although there is strong evidence that they do exist. AIMS. We performed a pilot study with the extr…
Asymmetric features in the protoplanetary disk MWC758
M. Benisty, A. Juhasz, A. Boccaletti +25
The study of dynamical processes in protoplanetary disks is essential to understand planet formation. In this context, transition disks are prime targets because they are at an adv…
The VORTEX project: first results and perspectives
Olivier Absil, Dimitri Mawet, Christian Delacroix +15
(abridged) Vortex coronagraphs are among the most promising solutions to perform high contrast imaging at small angular separations. They feature a very small inner working angle,…
A near-infrared interferometric survey of debris-disc stars. IV. An unbiased sample of 92 southern stars observed in H-band with VLTI/PIONIER
Steve Ertel, Olivier Absil, Denis Defrere +8
Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regi…
Searching for faint companions with VLTI/PIONIER. II. 92 main sequence stars from the Exozodi survey
Lindsay Marion, Olivier Absil, Steve Ertel +6
The Exozodi survey aims to determine the occurrence rate of bright exozodiacal discs around nearby main sequence stars using infrared interferometry. Although the Exozodi survey ta…
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…
