Li-rich Giants Identified from LAMOST DR8 Low-resolution Survey

B Cai, X Kong, J Shi, Q Gao, Y Bu… - The Astronomical Journal, 2023 - iopscience.iop.org
A small fraction of giants possess photospheric lithium (Li) abundance higher than the value
predicted by the standard stellar evolution models, and the detailed mechanisms of Li …

Convective mixing: the formation channel of Li-rich giants

XF Li, JR Shi, Y Li, HL Yan… - Monthly Notices of the …, 2024 - academic.oup.com
Increasing observed data indicate that part of giants has abnormally high lithium (Li) inside
their surface, and their proportion is around 1 per cent. Instead of pursuing the feasible …

The physical mechanism for the formation of lithium-rich red clump stars: Rotation, thermohaline mixing, and internal gravity waves

FW Wu, HF Song, G Meynet, A Maeder, JR Shi… - Astronomy & …, 2025 - aanda.org
Context. About 0.2–2% of red clump stars are revealed as Lithium-rich stars and thus the
surface abundance of lithium clearly increases in some red clump stars. The physical …

Study of a Red Clump Giant, KIC 11087027, with High Rotation and Strong Infrared Excess—Evidence of Tidal Interaction for High Lithium Abundance

R Singh, A Mallick, BE Reddy… - The Astrophysical …, 2024 - iopscience.iop.org
This Letter presents results from Kepler photometric light curves and a high-resolution
spectroscopic study of a super-Li-rich giant KIC11087027. Using the light-curve analysis, we …

The Impact of Nova Outbursts on the Chemical Abundance of the Interstellar Medium

G He, C Zhu, G Lü, L Li, S Guo, H Liu… - Research in Astronomy …, 2024 - iopscience.iop.org
Nova outbursts are the results of thermonuclear runaways, which occur when sufficient
material accretes on the surfaces of white dwarfs (WDs). Using the MESA code, we construct …

Novae: An Important Source of Lithium in the Galaxy
