Aims. We address the existence and origin of the lithium (Li) desert, a region in the Li–Teff plane sparsely populated by stars. Here we analyze some of the explanations that have been suggested for this region, including mixing in the late main sequence, a Li dip origin for stars with low Li abundances in the region, and a possible relation with the presence of planets. Methods. To study the Li desert, we measured the atmospheric parameters and Li abundance of 227 late-F dwarfs and subgiants… 
Exploring the production and depletion of lithium in the Milky Way stellar disk
Despite the recent availability of large samples of stars with high-precision Li abundances, there are many unanswered questions about the evolution of this unique element in the Galaxy and in the
The GALAH survey: a new constraint on cosmological lithium and Galactic lithium evolution from warm dwarf stars
Lithium depletion and enrichment in the cosmos is not yet well understood. To help tighten constraints on stellar and Galactic evolution models, we present the largest high-resolution analysis of
High-resolution Spectroscopic Study of Dwarf Stars in the Northern Sky: Lithium, Carbon, and Oxygen Abundances
Abundances of lithium, carbon, and oxygen have been derived using spectral synthesis for a sample of 249 bright F, G, and K Northern Hemisphere dwarf stars from the high-resolution spectra acquired
Theoretical Predictions of Surface Light Element Abundances in Protostellar and Pre-Main Sequence Phase
Theoretical prediction of surface stellar abundances of light elements–lithium, beryllium, and boron–represents one of the most interesting open problems in astrophysics. As well known, several
A high binary fraction for the most massive close-in giant planets and brown dwarf desert members
Stellar multiplicity is believed to influence planetary formation and evolution, although the precise nature and extent of this role remain ambiguous. We present a study aimed at testing the role
Lithium and beryllium in the Gaia-Enceladus galaxy
Data from Gaia DR2 and The Apache Point Observatory Galactic Evolution Experiment surveys revealed a relatively new component in the inner Galactic halo, which is likely the dynamical remnant of a
Emerging trends in metallicity and lithium properties of debris disc stars
Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently studied. In this paper
Lyα Observations of High Radial Velocity Low-mass Stars Ross 1044 and Ross 825
The discovery of habitable zone (HZ) planets around low-mass stars has highlighted the need for a comprehensive understanding of the radiation environments in which such planets reside. Of particular
The Peculiar Chemical Pattern of the WASP-160 Binary System: Signatures of Planetary Formation and Evolution?
Wide binary stars with similar components hosting planets provide a favorable opportunity for exploring the star–planet chemical connection. We perform a detailed characterization of the solar-type
Chemical Composition of Bright Stars in the Continuous Viewing Zone of the TESS Space Mission
Accurate atmospheric parameters and chemical composition of stars play a vital role in characterizing physical parameters of exoplanetary systems and understanding of their formation. A full


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
Lithium abundances for 185 main-sequence stars - Galactic evolution and stellar depletion of lithium
We present a survey of lithium abundances in 185 main- sequence field stars with Teff between 5600 and 6600 K and [Fe/H] from -1.4 to +0.2 based on high-resolution spectra of 130 stars and a
Li abundances in F stars: planets, rotation, and Galactic evolution
Aims. We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective temperatures hotter than the Sun, and on the
Li depletion in solar analogues with exoplanets - Extending the sample
Aims. We want to study the effects of the formation of planets and planetary systems on the atmospheric Li abundance of planet host stars. Methods. In this work we present new determinations of
Lithium abundance in the metal-poor open cluster NGC 2243
Context. Lithium is a fundamental element for studying the mixing mechanisms acting in the stellar interiors, for understanding the chemical evolution of the Galaxy and the Big Bang nucleosynthesis.
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.
Correlation between lithium abundances and ages of solar twin stars
We want to determine the lithium abundances of solar twin stars as a function of stellar age to provide constraints for stellar evolutions models and to investigate whether there is a connection
Lithium depletion and rotation in main-sequence stars
Lithium abundances were measured in nearly 200 old disk-population F stars to examine the effects of rotational braking on the depletion of Li. The sample was selected to be slightly evolved off the
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).
Lithium abundances of the local thin disc stars
Lithium abundances are presented for a sample of 181 nearby F and G dwarfs with accurate Hipparcos parallaxes. The stars are on circular orbits about the Galactic centre and, hence, are identified as
