The evolution on the AGB and beyond is reviewed with respect to the origin of Wolf-Rayet central stars. We focus on thermal pulses due to their particular importance for the evolution of hydrogen deficient stars. It is shown that overshoot applied to all convection regions is a key ingredient to model these objects leading to intershell abundances already close to the surface abundances of Wolf-Rayetcentral stars. In contrast to standard evolutionary calculations, overshoot models do show… Expand

Post-AGB Stars
The final phase of the evolution of low- and intermediate-mass stars is characterized by rapid changes in the structure and properties of the star and its circumstellar envelope (CSE); see Chapter 2.Expand
H- and He-burning central stars and the evolution to white dwarfs
The structure and evolution of central stars of planetary nebulae (CSPNe) is reviewed. CSPNe represent the rapid transitional stage between the Asymptotic Giant Branch (AGB) and the white-dwarfExpand
The formation and evolution of hydrogen-deficient post-AGB white dwarfs: The emerging chemical profile and the expectations for the PG 1159-DB-DQ evolutionary connection
We explore the formation and evolution of hydrogen-deficient post-AGB white dwarfs. To this end, we compute the complete evolution of an initially 2.7 Mstar from the zero-age main sequence throughExpand
Nucleosynthesis of Low and Intermediate-mass Stars
The asymptotic giant branch (AGB) is the last nuclear-burning phase for low and intermediate-mass stars with initial masses between about 0.8 to 8 solar masses. The AGB phase of evolution is veryExpand
Post-AGB Stars
▪ Abstract In this contribution, a review is presented on the ample data obtained on post-AGB stars, both on the central stars and their circumstellar material. The fast evolutionary phase isExpand
Full evolutionary models for PG 1159 stars. Implications for the helium-rich O(He) stars
Aims. We present full evolutionary calculations appropriate to post-AGB PG 1159 stars for a wide range of stellar masses. Methods. We take into account the complete evolutionary stages of PG 1159Expand
The Elemental Abundances in Bare Planetary Nebula Central Stars and the Shell Burning in AGB Stars
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)Expand
New models for the evolution of Post-Asymptotic Giant Branch stars and Central Stars of Planetary Nebulae
The Post Asymptotic Giant Branch (AGB) phase is arguably one of the least understood phases of the evolution of low- and intermediate- mass stars. The two grids of models presently available areExpand
We present stellar evolutionary sequences for asymptotic giant branch (AGB) stars in the Magellanic Cloud clusters NGC 1978, NGC 1846, and NGC 419. The new stellar models for the three clusters matchExpand
Can pulsating PG 1159 stars place constraints on the occurrence of core overshooting
The present letter is aimed at exploring the influence of overshooting during the central helium burning in pre-white dwarf progenitors on the pulsational properties of PG 1159 stars. To this end weExpand


Prevention of high-luminosity carbon stars by hot bottom burning
CNO abundances are presented for theoretical models of asymptotic giant branch stars of 4, 5, and 6 M ○. with Z=0.02 and Z=0.001. Self-consistent stellar evolutionary models were computed, startingExpand
Evolution of Low- and Intermediate-Mass Stars to the End of the Asymptotic Giant Branch with Mass Loss
Stars with initial masses in the range 0.89≤M/M ○. ≤5.0 have been evolved from the main-sequence phase through to the end of the asymptotic giant branch (AGB). The calculations were done withExpand
On the frequency of planetary nebula nuclei powered by helium burning and on the frequency of white dwarfs with hydrogen-deficient atmospheres
The evolutionary behavior of a model central star of a planetary nebula is examined as a function of the phase in its nuclear burning cycle when its progenitor leaves the asymptotic giant branch forExpand
Late stages of stellar evolution. II: Mass loss and the transition of asymptotic giant branch stars into hot remnants
We have computed the transition of asymptotic branch giants of 0.8 and 1.0 M/sub sun/ into remnants of 0.565, 0.553, and 0.546 M/sub sun/ by means of mass loss which removed the stellar envelopes inExpand
Central star temperatures of optically thick planetary nebulae and a distance-independent test of dredge-up theory
The effective temperatures are calculated and the V magnitudes are predicted for the central stars of 62 optically thick planetary nebulas by forcing agreement between the hydrogen and ionized heliumExpand
Further adventures of a thermally pulsing star
Eight more thermal pulses have been calculated for a 7 M/sub sun/ model star with a carbon-oxygen core of mass 0.95--0.96 M/sub sun/. From the 10th to the 18th pulse, the maximum helium-burningExpand
White dwarfs have been known for slightly more than fifty years; with their planet-like diameters, and stellar-like masses their densities are enormously much higher than those of ‘normal’ stars.Expand
