Spectroscopic survey of post-AGB star candidates.

PEREIRA C.B. and MIRANDA L.F.

Abstract (from CDS):

Our goal is to establish the true nature of post-AGB star candidates and to identify new post-AGB stars. We used low resolution optical spectroscopy and we compared the spectra of the candidate post-AGB stars with those of stars in the library specta available in the literature and with spectra of ``standard'' post-AGB stars, and direct imaging in narrow-band filters. Spectra were obtained for 16 objects: 14 objects have not been observed previously and 2 objects are already known post-AGB stars used as ``standards'' for identification. From the spectra we identify: six new post-AGB stars with spectral types between G5 and F5, two HII regions the morphology of which is revealed in the direct images for the first time, a G giant with infrared emission, a young stellar object, a probable post-AGB star with emission lines and three objects for which the classification is still unclear. As a whole, our results provide new, reliable identifications for 10 objects among listed post-AGB star candidates.
