WebWe present infrared polarimetric images that demonstrate that the T Tauri star HL Tau is not seen in direct light at lambda <= 2.2 mu m. The position of the intensity centroid moves monotonically southwest from V (0.555 mu m) through J (1.25 mu m) and H (1.65 mu m) to K (2.2 mu m) wave bands. Furthermore, the mean position of the J, H, and K polarimetric …
