The circumstellar disk HD169142: gas, dust and planets acting in concert?
A. Pohl, M. Benisty, P. Pinilla +33
HD169142 is an excellent target to investigate signs of planet-disk interaction due to the previous evidence of gap structures. We performed J-band (~1.2μm) polarized intensity…
Performance of the extreme-AO instrument VLT/SPHERE and dependence on the atmospheric conditions
J. Milli, D. Mouillet, T. Fusco +10
SPHERE is the high-contrast exoplanet imager and spectrograph installed at the Unit Telescope 3 of the Very Large Telescope. After more than two years of regular operations, we ana…
Modelling astronomical adaptive optics performance with temporally-filtered Wiener reconstruction of slope data
Carlos M. Correia, Charlotte Z. Bond, Jean-François Sauvage +3
We build on a long-standing tradition in astronomical adaptive optics (AO) of specifying performance metrics and error budgets using linear systems modeling in the spatial-frequenc…
Quantifying telescope phase discontinuities external to AO-systems by use of Phase Diversity and Focal Plane Sharpening
Masen Lamb, Carlos Correia, Jean-Francois Sauvage +7
We propose and apply two methods to estimate pupil plane phase discontinuities for two realistic scenarios on VLT and Keck. The methods use both Phase Diversity and a form of image…
Discovery of a warm, dusty giant planet around HIP65426
G. Chauvin, S. Desidera, A. -M. Lagrange +120
The SHINE program is a large high-contrast near-infrared survey of 600 young, nearby stars. It is aimed at searching for and characterizing new planetary systems using VLT/SPHERE's…
Exploring dust around HD142527 down to 0.025" / 4au using SPHERE/ZIMPOL
H. Avenhaus, S. P. Quanz, H. M. Schmid +25
We have observed the protoplanetary disk of the well-known young Herbig star HD 142527 using ZIMPOL Polarimetric Differential Imaging with the VBB (Very Broad Band, ~600-900nm) fil…
