Lithium in field Am and normal A–F-type stars

, 2006
Preliminary abundances of lithium and a few other elements have been obtained for 31 field Am stars with good Hipparcos parallaxes, as well as for 36 normal A and F stars. Radial and projected rotational velocities were determined as well.

Revisiting the Li Abundances of Stars with and without Detected Planets from High-resolution Spectroscopy

The Astrophysical Journal
Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference in the Li abundance between planet-host stars (HSs) and isolated stars (ISs) with no detected planets, we ...

The lithium-rich giant stars puzzle: New observational trends for a general-mass-loss scenario

The existence of one percent of lithium-rich giant stars among normal, lithium-poor giant stars continues to be poorly explained. By merging two catalogues, one containing 10,535 lithium-rich giant stars with lithium abundances ranging from 1.5 to 4.9 ...

Probing Binary Architectures of Lithium-rich Giants in GALAH with COSMIC and Stellar Models

The Astrophysical Journal
Surface lithium is depleted when a star goes through the first dredge-up phase, yet 1% of red giants are found to be Li rich. The formation mechanism for these remains uncertain. We combine observational constraints from Galactic Archaeology with HERMES (
