Abstract

We have obtained new optical spectra with the ESO/VLT of the final helium flash star, V605 Aql. These spectra, indicate that V605 Aql has evolved significantly in only 80 years. It now has a T _eff ∼95,000 K and has abundances similar to those seen in [WC] central stars but not to those of a typical RCB star.
