Description
The circumstellar disk around the Herbig Ae/Be star HD169142 is a well-studied object which shows structures on multiple wavelength ranges. Moreover, HD169142 harbors the most promising proto-planet candidate.
We present new SPHERE/ZIMPOL data which distinctly deviate from the established picture developed for this object.
Based on these new observations as well as high-resolution ALMA observations and further archival data, we built a new
model for this disk. These new eyes, namely SPHERE and ALMA, in combination with 3D radiative transfer simulations
strongly indicate that we are witness to previously undetected planet-disk interactions in HD169142.
