Abstract
Millimeter wavelength, aperture synthesis observations of the bipolar outflow region associated with Herbig-Haro objects HH 7-11 obtained at Owens Valley are presented. The circumstellar continuum emission, the circumstellar molecular-line emission, and the high-velocity CO emission from the blue-shifted lobe of the HH 7-11 bipolar outflow are analyzed. It is observed that the emission is resolved into a binary source; one source coincides with the embedded near-IR source SVS 13 and the companion to the southwest has been detected only at 98 and 110 GHz. It is suggested that, due to the lack of near-IR luminosity, the companion may be a true protostar and that the high-velocity molecular gas is distributed in an elongated, expanding, and highly inhomogeneous shell which surrounds a cavity containing the HH objects. 36 references.
