Spectroscopic observations of two proto planetary-nebulae candidates: SS73 56 & Hen 2-79.

Abstract (from CDS):

We report new spectroscopic observations of two proto planetary-nebulae candidates: SS73 56 and Hen 2-79 between 3200Å and 8000Å. From the measurements of several forbidden and permitted emission lines of single ionized iron, we derived the color excess and the excitation temperature. We discuss the nature of the two objects based on data obtained. The iron spectrum closely resembles η Car but the absence or the weakness of [NII]5754Å compared to η Car reduces the possibility of being a LBV object. We also compare the two objects with the peculiar emission-line object SS73 11 that was recently analyzed by us.
