Abstract

We present millimeter-wave interferometric and single-dish observations of IRAS 16293-2422 in the CS J = 2 → 1 line. The images reveal clumpy, shell-like structures which appear to be limb-brightened emission from dense gas at the perimeter of the molecular outflow observed in CO. These structures may be ambient cloud material swept up by a stellar wind into dense shells. At all velocities where CS is detected, features related to the outflow are observed. Most of the mass of the outflow system is contained in low-velocity shells.
