SPHERE J-band linearly polarized intensity image (Qϕ) of the disk of UX Tau C. The image is binned by a factor of 2 to improve contrast. The data are shown in linear stretch, and the scale is absolute in detector units (ADU). The disk is faint and compact. The disk position angle is PA = 5° ±2°. The axis ratio suggests an inclination larger than i = 60°. The disk is detected over , or ∼19 au.
