High-resolution spectroscopic observations of post-asymptotic giant branch candidates from the Edinburgh-Cape Survey

This is the authors' abstract. We don't add key points for this paper.

High spectral resolution (R∼ 40 000) and signal-to-noise optical spectra, obtained at the Very Large Telescope (VLT), are presented for three post—asymptotic giant branch (AGB) candidates selected from the Edinburgh—Cape (EC) Faint Blue Object Survey. The stellar atmospheric parameters and chemical compositions, derived using sophisticated non-local thermodynamic equilibrium calculations, reveal that EC 14102-1337 and EC 20068-7324 are both in an evolved post—horizontal branch (HB) evolutionary state. However, EC 11507-2253 is most likely a post-AGB star.
