Paper Abstract

We present images of the (v= 1 — 0) S(1) transition of molecular hydrogen at 2.121 µm towards T Tauri, observed with the SHARP II camera attached to the ADONIS adaptive optics system at the European Southern Observatory’s 3.6 m telescope on La Silla, Chile. With an image scale of 0"1 per pixel, we could cover a field of 25" in each exposure. Positioning T Tauri successively in the four quadrants of the detector, we obtained a 35" mosaic centered on the star. In the 2.12 µm continuum, the 0"7 binary is easily resolved. In continuum-subtracted images in the emission line, we detect a very complex structure: strong emission at the position of the infrared companion, a very bright knot 2-3" northwest, three thin filaments, strong emission extending 10" south towards Burnham’s nebula, and a faint arc 10" north. While the material north and south of the stars may be associated with an outflow, we argue that the knots and filaments may be shock-excited material in the equatorial plane. They could be either tidal tails caused by the interaction of the two star-disk systems (T Tau N and T Tau S), accretion streams from the inner edge of the circumbinary disk, or spiral shocks in this disk.
