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…
Three years of SPHERE: the latest view of the morphology and evolution of protoplanetary discs
Antonio Garufi, Myriam Benisty, Tomas Stolker +11
Spatially resolving the immediate surroundings of young stars is a key challenge for the planet formation community. SPHERE on the VLT represents an important step forward by incre…
Variable dynamics in the inner disk of HD 135344B revealed with multi-epoch scattered light imaging
Tomas Stolker, Mike Sitko, Bernard Lazareff +12
We present multi-epoch VLT/SPHERE observations of the protoplanetary disk around HD 135344B (SAO 206462). The -band scattered light imagery reveal, with high spatial resolution…
Investigation of the inner structures around HD169142 with VLT/SPHERE
R. Ligi, A. Vigan, R. Gratton +47
We present observations of the Herbig Ae star HD169142 with VLT/SPHERE instruments InfraRed Dual-band Imager and Spectrograph (IRDIS) ( and bands) and the Integral Fie…
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…
Polarized scattered light from self-luminous exoplanets. Three-dimensional scattering radiative transfer with ARTES
Tomas Stolker, Michiel Min, Daphne M. Stam +3
Direct imaging has paved the way for atmospheric characterization of young and self-luminous gas giants. Scattering in a horizontally-inhomogeneous atmosphere causes the disk-integ…
