  We have obtained new near-infrared images of both GG Tau and UY Aur
circumbinary disks with the polarimetric modes of NICMOS aboard the Hubble
Space Telescope. The 1 micron intensity map of GG Tau reveals a more complete
elliptical shape than in previous ground-based images. Its eastern and western
sides are definitely asymmetric. Our image strongly supports the ring geometry
proposed by Guilloteau, Dutrey & Simon (1999) on the basis of their millimetre
interferometry images: a geometrically thick and sharply edged ring surrounding
an empty gap around the binary. Around UY Aur, we identify structures that are
in excellent agreement with the optical images of M\'enard et al. (1999), which
confirms that the inclination of the system to the line-of-sight is about 60
degrees. We also find tentative new structures closer to the stars.
