THE MOLECULAR ENVELOPE AROUND T-TAURI AND THE NATURE OF NGC-1555

We present maps of the (CO)-C-12(3-2) and (CO)-O-18(2-1) emission arou nd T Tauri. By comparison of the two lines measured with similar spati al resolution we are able to discriminate between the different compon ents of molecular circumstellar material and to derive constraints for possible source models. In particular we are able to trace the outflo wing molecular components. We propose a multiple outflow system with s tellar wind envelope interaction to explain the morphology and dynamic s of the (CO)-C-12(3-2) and (CO)-O-18(2-1) emitting gas.
