The first observations of T-Tauri stars in the (12)CO (6 to 5) line are reported. The observations trace the dynamics of warm and dense gas in a scale below 10 arcseconds. The CO submillimeter emission probably originates in the interaction of a stellar wind with a high column density of molecular material close to the stars. Additional CO data show that the emission extensions and line widths in T-Tau and HL-Tau are not consistent with Keplerian rotation or residual infall but can be explained by warm, dense, slowly outflowing material. The molecular outflow rate is at least 10 to the -6th power of the solar mass per year for T-Tau and 10 to the -7th power of the solar mass per year for HL-Tau, and may contribute to the dissipation of the clouds in which these stars formed. It is concluded that the dust associated with the warm molecular outflows accounts for a substantial fraction of T-Tau's and HL-Tau's far infrared continuum emission.
