Episodic lithium production by extra-mixing in red giants
P. A. Denissenkov, A. Weiss
The recent discovery of low-mass red giants with enhanced atmospherical Li abundance in galactic low-metallicity stellar clusters adds to the mysterious phenomenon of the Li-rich g…

Evolution and surface abundances of red giants experiencing deep mixing
Achim Weiss, Pavel A. Denissenkov, Corinne Charbonnel
We have calculated the evolution of low metallicity red giant stars under the assumption of deep mixing between the convective envelope and the hydrogen burning shell. We find that…
