HD 168625 (B9-A0 Ia) was classified as a post-AGB star and also as a luminous blue variable. We have analysed the high resolution optical spectra of HD 168625...
Spectroscopy of Planetary Nebulae at the Bright End of the Luminosity Function
We have obtained spectra of 8 luminous planetary nebulae (PNe) in M31 and 4 in the Large Magellanic Cloud with the goal of understanding their properties and...
Spectroscopy of Pluto at six longitudes, 380-930 nm
We have obtained spectra of the Pluto-Charon pair (unresolved) in the wavelength range 380-930 nm with resolution ~450 at six roughly equally spaced longitudes...
Spectroscopy of Post-AGB A-Supergiant HD 101584 (IRAS 11385-5517)
In the high resolution optical spectra we identified forbidden lines of [OI] and [CI], which indicate the presence of low excitation nebula. There are many...
Spectroscopy of Post-AGB Candidate HD 331319 (IRAS 19475+3119)
HD 331319 is a F3 Ib star with a detached cold circumstellar dust shell with far-IR colours similar to planetary nebulae. From an analysis of high resolution...
Spectroscopy of Post-AGB Candidate IRAS 10215-5916
IRAS 10215-5916 was classified as a post-AGB star and also as a massive red supergiant. It was also found to be a spectroscopic binary. In our high resolution...
