Polarimetric differential imaging data of HIP 79977 with the VBB filter (590–880 nm). The mean images show polarized flux Stokes Q (left) and U (right) after 3 × 3 binning. The position of the star is marked by an asterisk in orange. The image region located within a white stellarcentric circle with a radius of ~0.12′′ is dominated by the strong speckles variations. The color-bar shows the counts per binned pixel.
