(Left) Spectra of the observed molecular lines in the envelope of IK Tau. The emission is summed over all SMA baselines. The vertical line indicates the VLSR = 34 km s-1 stellar velocity. (right) The stellar continuum and dust emission (color) and integrated CO(2–1) line emission (contours) of IK Tau. The contours are drawn at 10,20,40,80, and 160 Jy beam-1 km s-1.
