Part of the International Astronomical Union / Union Astronomique Internationale book series (IAUS, volume 131)
Within a spectroscopic study of some southern planetary nebulae, we have observed 32 objects. Some of them are symbiotic or suspected symbiotic stars, and one (He 2–61) is evidently not an emission object.
