Abstract

CCD images show that the reflection nebula associated with PV Cep is bipolar. From spectroscopy of this object as well as of the bipolar Boomerang Nebula we find low excited Herbig-Haro emission and indications for collimated high velocity flows along the polar axes of both nebulae. The central star of the Boomerang Nebula is probably double.
