HD 117214 debris disk: scattered-light images and constraints on the presence of planets
N. Engler, C. Lazzoni, R. Gratton +34
We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed…
The polarimetric imaging mode of VLT/SPHERE/IRDIS II: Characterization and correction of instrumental polarization effects
R. G. van Holstein, J. H. Girard, J. de Boer +31
Context. Circumstellar disks and self-luminous giant exoplanets or companion brown dwarfs can be characterized through direct-imaging polarimetry at near-infrared wavelengths. SPHE…
First resolved observations of a highly asymmetric debris disc around HD 160305 with VLT/SPHERE
Clément Perrot, Philippe Thebault, Anne-Marie Lagrange +36
Context. Direct imaging of debris discs gives important information about their nature, their global morphology, and allows us to identify specific structures possibly in connectio…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor. III. On-sky validation in VLT/SPHERE
A. Vigan, M. N'Diaye, K. Dohlen +12
Second-generation exoplanet imagers using extreme adaptive optics and coronagraphy have demonstrated their great potential for studying close circumstellar environments and for det…
SPHERE: the exoplanet imager for the Very Large Telescope
J. -L. Beuzit, A. Vigan, D. Mouillet +108
Observations of circumstellar environments to look for the direct signal of exoplanets and the scattered light from disks has significant instrumental implications. In the past 15…
