Evolution of Asymptotic Giant Branch Stars
▪ Abstract The current status of modeling the evolution and nucleosynthesis of asymptotic giant branch (AGB) stars is reviewed. The principles of AGB evolution have been investigated in recent yearsExpand

The supernova channel of super-AGB stars
We study the late evolution of solar metallicity stars in the transition region between white dwarf formation and core collapse. This includes the super-asymptotic giant branch (super-AGB, SAGB)Expand

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

Evolution and Yields of Extremely Metal-poor Intermediate-Mass Stars
Intermediate-mass stellar evolution tracks from the main sequence to the tip of the AGB for five initial masses (2-6 M☉) and metallicity Z = 0.0001 have been computed. The detailed one-dimensionalExpand

On the α formalism for the common envelope interaction
The α formalism is a common way to parametrize the common envelope interaction between a giant star and a more compact companion. The α parameter describes the fraction of orbital energy released byExpand

The dependence of the evolution of SN type Ia progenitors on the C burning rate uncertainty and parameters of convective boundary mixing
Evolution of a supernova type Ia progenitor requires formation of a CO white dwarf, which implies a dependence on the C burning rate (CBR). It can also be affected by the recently identifiedExpand

Very Large Excesses of 18 O in Hydrogen-deficient Carbon and R Coronae Borealis Stars: Evidence for White Dwarf Mergers
We have found that at least seven hydrogen-deficient carbon (HdC) and R Coronae Borealis (RCB) stars, have 16O/18O ratios close to and in some cases less than unity, values that are orders ofExpand

Dredge-up and Envelope Burning in Intermediate-Mass Giants of Very Low Metallicity
The evolution of intermediate-mass stars at very low metallicity during their final thermal pulse asymptotic giant branch (AGB) phase is studied in detail. As representative examples, models withExpand

A Search for Nitrogen-enhanced Metal-poor Stars*
Theoretical models of very metal-poor intermediate-mass asymptotic giant branch (AGB) stars predict a large overabundance of primary nitrogen. The very metal-poor, carbon-enhanced, s-process-richExpand
