Abstract: 
High-angular resolution (∼0″.4) VLA observations of HL Tauri at 1.3 cm reveal the existence of an elongated structure (∼1″.4 × 0″.6, or ∼ 200 × 80 AU at a distance of 140 pc) surrounding the star. The physical dimensions and the flux density of this source (2.9 ± 0.4 mJy) suggest that the 1.3 cm emission arises from dust in a protoplanetary disk. However, the orientation of the major axis of the structure (position angle =22° ± 4°) with respect to the orientation of previously studied phenomena in the region does not allow a definitive determination of the nature of the object.
