The lithium abundances for 378 G/K giants are derived with non-local thermodynamic equilibrium correction considered. Among these are 23 stars that host planetary systems. The lithium abundance is investigated, as a function of metallicity, effective temperature, and rotational velocity, as well as the impact of a giant planet on G/K giants. The results show that the lithium abundance is a function of metallicity and effective temperature. The lithium abundance has no correlation with… 
Lithium in Stellar Atmospheres: Observations and Theory
Of all the light elements, lithium is the most sensitive indicator of stellar evolution. This review discusses current data on the abundance of lithium in the atmospheres of A-, F-, G-, and K-stars
Parameters and abundances for 1133 stars of spectral types F, G, and K of luminosity class III have been derived. In terms of stellar parameters, the primary point of interest is the disagreement
Lithium in red giant stars: Constraining non-standard mixing with large surveys in the Gaia era
Context. Li is extensively known to be a good tracer of non-standard mixing processes occurring in stellar interiors. Aims. We present the results of a new large Li survey in red giant stars and
On Lithium-6 as a Diagnostic of the Lithium-enrichment Mechanism in Red Giants
High lithium-7 (7Li) abundances in giants are indicative of nonstandard physical processes affecting the star. Mechanisms that could produce this signature include contamination from an external
Lithium-rich Giants in LAMOST Survey. I. The Catalog
Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge up process (FDU). Yet a small fraction of giant stars are still found to preserve a
On the observational characteristics of lithium-enhanced giant stars in comparison with normal red giants
With an aim to shed light on the origin of Li anomaly observed in a small fraction of red giants, we carried out a spectroscopic study on the observational characteristics of selected 20 bright
Spectroscopic study on the beryllium abundances of red giant stars
An extensive spectroscopic study was carried out for the beryllium abundances of 200 red giants (mostly of late G and early K type), which were determined from the near-UV Be II 3131.066 line based
Far-infrared study of K giants in the solar neighborhood: Connection between Li enrichment and mass-loss
We searched for a correlation between the two anomalous properties of K giants: Li enhancement and IR excess from an unbiased survey of a large sample of RGB stars. A sample of 2000 low-mass K giants
The AMBRE Project: Constraining the lithium evolution in the Milky Way
Context. The chemical evolution of lithium in the Milky Way represents a major problem in modern astrophysics. Indeed, lithium is, on the one hand, easily destroyed in stellar interiors, and, on the
The cool giant HD 77361—a super Li-rich star
Super Li-rich stars form a very small and enigmatic group whose existence cannot be explained in terms of the standard stellar evolution theory. The goal of our study is to check the reality of this


Lithium abundances and rotational behavior for bright giant stars
Aims. We study the links possibly existing between the lithium content of bright giant stars and their rotational velocity. Methods. We performed a spectral analysis of 145 bright giant stars
Lithium Abundances in a Sample of Planet-hosting Dwarfs
This work presents a homogeneous determination of lithium abundances in a large sample of giant-planet-hosting stars (N = 117) and a control sample of disk stars without detected planets (N = 145).
A Search for Lithium-rich Giant Stars
Lithium abundances or upper limits have been determined for 644 bright G-K giant stars selected from the DDO photometric catalog. Two of these giants possess surface lithium abundances approaching

Aims. We present Lithium abundance determination for a sample of K giant stars in the galactic bulge. The stars presented here a re the only 13 stars with detectable Lithium line (6767.18A) among∼400
Lithium abundances in nearby FGK dwarf and subgiant stars: internal destruction, Galactic chemical evolution, and exoplanets
We derive atmospheric parameters and lithium abundances for 671 stars and include our measurements in a literature compilation of 1381 dwarf and subgiant stars. First, a “lithium desert” in the
Enhanced lithium depletion in Sun-like stars with orbiting planets
Li abundances are reported for an unbiased sample of solar-analogue stars with and without detected planets to find that the planet-bearing stars have less than one per cent of the primordial Li abundance, while about 50% of the solar analogueswithout detected planets have on average ten times more Li.

We have determined precise stellar parameters and lithium abundances in a sample of 117 stars with basic properties very similar to the Sun. This sample selection reduces biasing effects and
