Lithium Abundances in Giants as a Function of Stellar Mass: Evidence for He Flash as the Source of Li Enhancement in Low-mass Giants

In this work, we studied the distribution of lithium abundances in giants as a function of stellar mass. We used a sample of 1240 giants common among Kepler photometric and LAMOST medium-resolution ( R ≈ 7500) spectroscopic survey fields. The asteroseismic Δ P –Δ ν diagram is used to define core He-...
