The peculiar object He 2-467.
Abstract
He has been classified as a planetary nebula. However, the spectrum of this object shows emission lines superposed on the absorption spectrum of a G-type star. Image tube spectrograph and scanner observations of the emission and absorption features are presented. The emission spectrum is unusual in that no forbidden lines are seen, and the He I singlet to triplet ratios do not agree with recombination theory.
