Synthesis of Organic and Inorganic Compounds in Asymptotic Giant Branch Stars
GalaxiesAfter the synthesis of carbon in the core of asymptotic giant branch (AGB) stars, carbon is dredged up to the surface by convection. Many carbon-based molecules are formed in the subsequently developed stellar wind.

Evolution and nucleosynthesis of helium-rich asymptotic giant branch models
, 2015 There is now strong evidence that some stars have been born with He mass fractions as high as $Y \approx 0.40$ (e.g., in $\omega$ Centauri). However, the advanced evolution, chemical yields, and final fates of He-rich stars are largely unexplored.

Li Evolution among Stars of Low/Intermediate Mass: the Metal-deficient Open Cluster NGC 2204
The Astronomical JournalWe have analyzed high-dispersion spectra in the Li 6708 Å region for 167 stars within the anticenter cluster NGC 2204. From 105 probable members, abundance analysis of 45 evolved stars produces [Fe/H] = −0.40 ± 0.12, [Si/Fe] = 0.14 ± 0.12, [Ca/Fe] = 0.29

Dynamical Models of Asymptotic-Giant-Branch Stars [PDF]
Symposium - International Astronomical Union, 1974 The dynamical behaviour of the envelopes of four asymptotic-giant-branch stars of composition (X, Z)=(0.68, 0.02) and luminosity log L/L⊙ = 3.41, 3.60, 3.85 and 4.14 has been studied. At log L/L⊙ = 3.41, the envelope pulsates in the first-overtone mode and exhibits properties similar to those of the Mira variables.
