Scientific paper

The first high resolution, two-dimensional, near-infrared (J to L bands) images of the young stellar object HL Tau have been taken using an infrared camera. These images, particularly the H/K two-color image, convincingly suggest that light from the central young star scatters off a surrounding geometrically flaring disk. The disk would not be edge-on, but tilted by 20-30 deg toward the line of sight. Its radius is about 500 AU and its mass is at least 0.07 solar masses, depending on grain composition.
