Comparison of the disk structures in HD 120326 detected in scattered light (SPHERE, 1.6 μm) and in thermal emission (ALMA, 1.3 mm). On the left, we show the polarized intensity SPHERE image with in overlay the contours of the inner belt determined for a signal level of 2 mJy/arcsec² on this image convolved with a gaussian to obtain smooth contours. The contours are added on the total intensity SPHERE image (middle) and on the zoom-out ALMA reconstructed image (right). In the middle image, we added a white arrow to point out the southwestern part of the second structure seen in total intensity, which does not overlap with the signal seen in polarized intensity.
