We have observed the protoplanetary disk of the well-known young Herbig starHD 142527 using ZIMPOL Polarimetric Differential Imaging with the VBB (VeryBroad Band, ~600-900nm) filter. We obtained two datasets in May 2015 and March2016. Our data allow us to explore dust scattering around the star down to aradius of ~0.025" (~4au). The well-known outer disk is clearly detected, athigher resolution than before, and shows previously unknown sub-structures,including spirals going inwards into the cavity. Close to the star, dustscattering is detected at high signal-to-noise ratio, but it is unclear whetherthe signal represents the inner disk, which has been linked to the twoprominent local minima in the scattering of the outer disk, interpreted asshadows. An interpretation of an inclined inner disk combined with a dust halois compatible with both our and previous observations, but other arrangementsof the dust cannot be ruled out. Dust scattering is also present within thelarge gap between ~30 and ~140au. The comparison of the two datasets suggestsrapid evolution of the inner regions of the disk, potentially driven by theinteraction with the close-in M-dwarf companion, around which no polarimetricsignal is detected.
