Aperture synthesis maps of HCN emission (J = 1 → 0, 88.631 GHz) toward the bipolar nebula S106 have been obtained with the Berkeley millimeter-wavelength interferometer. Spectral and spatial resolution were 4 km s-1 and 13arcsec. The HCN emission has a linear structure coincident with the dust lane seen in optical and infrared images of the nebula. The molecular gas bisects the two lobes of radio continuum emission from the ionized gas and is centered on the position of the infrared point source which is presumed to be the exciting star. These results support the idea that a disk of high-density neutral gas surrounds the exciting star and has directed the ionized gas into the observed bipolar shape. Estimates of the dimensions, the total mass and the angular momentum per unit mass of this disk are presented.
