Abstract / Description:We present spatially resolved near IR observations of the H_{2} emission in the vicinity of T Tau N using SINFONI, the integral field spectrograph of the VLT. The gas is detected as a ring-like structure within Ëœ80-100 AU from the star. The velocities of the H_{2} are close to the systemic velocity of T Tau N, and an analysis of the excitation mechanisms plays in favor of a scenario where the H_{2} is linked to the atmosphere of the circumstellar disk. The possible excitation scenarii are evoked here. Eventually, when detected in the disk, H_{2} is also a strong tracer of the status of potential planet formation.
