Distribution and evolution of Li abundance in red clump stars can be explained by the internal gravity waves

Xuefeng Li, Jianrong Shi, Yan Li +2

The study of Li phenomena in red clump (RC) stars can give us a deeper understanding of the structure and evolution of stars. \citet{2022ApJ...933...58C} explained the RC Li abunda…

Convective Mixing: The Formation Channel of Li-rich Giants

Xuefeng Li, Jianrong Shi, Yan Li +2

Increasing observed data indicate that part of giants has abnormally high lithium (Li) inside their surface, and their proportion is around 1%. Instead of pursuing the feasible mec…

Relations of rotation and chromospheric activity to stellar age for FGK dwarfs from Kepler and LAMOST

Lifei Ye, Shaolan Bi, Jinghua Zhang +9

The empirical relations between rotation period, chromospheric activity, and age can be used to estimate stellar age. To calibrate these relations, we present a catalog, including…
