We review the observed properties of extremely hot, hydrogen-deficient post-asymptotic giant branch (AGB) stars of spectral type (WC) and PG1159. Their H deficiency is probably caused by a (very) late helium-shell flash or an AGB final thermal pulse, laying bare interior stellar regions that are usually kept hidden below the hydrogen envelope. Thus, the photospheric elemental abundances of these stars allow us to draw conclusions about details of nuclear burning and mixing processes in the… Expand
Element Abundance Determination in Hot Evolved Stars
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes the hydrogenExpand
AGB star intershell abundances inferred from UV spectra of extremely hot post-AGB stars
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes the hydrogenExpand
Spectroscopic analysis of hot (pre-) white dwarfs
Context. About a quarter of all post-asymptotic giant branch (AGB) stars are hydrogen-deficient. Stellar evolutionary models explain the carbon-dominated H-deficient stars by a (very) late thermalExpand

Stellar yields and abundances: new directions from planetary nebulae
Abstract Planetary nebulae retain the signature of the nucleosynthesis and mixing events that occurred during the previous AGB phase. Observational signatures complement observations of AGB andExpand
(F)UV spectroscopy of the hybrid PG1159-type central stars of the planetary nebulae NGC 7094 and Abell43
Hydrogen-deficient post-AGB stars have experienced a late helium-shell flash that mixes the hydrogen-rich envelope and the helium-rich intershell (between hydrogen- and helium-burning shell). TheExpand
Discovery of photospheric argon in very hot central stars of planetary nebulae and white dwarfs
Context. We report the first discovery of argon in hot evolved stars and white dwarfs. We have identified the Ar vii 1063.55 A line in some of the hottest known (Teff = 95 000−110 000 K) centralExpand
The far-ultraviolet spectra of two hot PG1159 stars
PG1159 stars are hot, hydrogen-deficient (pre-) white dwarfs with atmospheres mainly composed of helium, carbon, and oxygen. The unusual surface chemistry is the result of a late helium-shell flash.Expand
The mass of helium in white dwarf stars and the formation and evolution of hydrogen-deficient post-AGB stars
We use two sets of ‘cradle-to-grave’ evolutionary calculations to investigate how the mass of the helium buffer layer between the CO core and the hydrogen-burning shell in thermally pulsingExpand
Sliding along the Eddington Limit -- Heavy-Weight Central Stars of Planetary Nebulae
Due to thermal pulses, asymptotic giant branch (AGB) stars experience periods of convective mixing that provide ideal conditions for slow neutron-capture nucleosynthesis. These processes are affectedExpand
