Abstract (from CDS):

High spectral resolution (R∼ 40000) 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.
