Zoom-in of the continuum (left) and Hα (right) polarization images showing the bar-like structure extending across NE-SW from the outer to the inner disk (whose outer edge is indicated with the red solid ellipse at ~2.5 au). The contrast has been varied to highlight the bar, and a Gaussian smoothing of 3 pixels in radius has been applied. +5σ and +6σ isocontours above the zero-polarization level are overplotted with white solid and dashed lines. The position of the central star is indicated with a cross and the resolution element with a dashed circle with diameter of 20 mas.
