R. ; Zuckerman, B. Abstract Interferometric measurements of CO and C-13O (J = 1-0) emission toward T Tauri verify the earlier detection of 0.01 solar masses of circumbinary gas. A disk is clearly resolved by the small beam. The high spatial and spectral resolution (0.26 km/s) data are consistent with disk gas in bound Keplerian orbits, nearly in the plane of the sky, around the central binary. The disk is oriented such that the rotation axis is inclined by about 26 deg to the earth-star line. The new measurements clearly indicate the presence of orbiting material outside of its orbit (100 AU) as well as inside, where a planetary system might form. Simultaneous 2.7 mm continuum observations yield a flux density of 75 mJy.
