A Search for New Objects in the Transition Phase Between Agb-Stars and Planetary Nebulae
Abstract
We present the first results of a spectroscopy survey of iras sources with colours similar to those of planetary nebulae. Two new planetary nebulae, some Hα emission line stars, one peculiar source which is probably a pre-Main-Sequence object and a new Seyfert I galaxy have been found.
