The solar chemical composition is an important ingredient in our understanding of the
formation, structure, and evolution of both the Sun and our Solar System. Furthermore, it is …

Context. The Kepler spacecraft is providing time series of photometric data with
micromagnitude precision for hundreds of AF type stars. Aims. We present a first general …

Multiple codes are available to derive atmospheric parameters and individual chemical
abundances from high-resolution spectra of AFGKM stars. Almost all spectroscopists have …

We present and discuss new determinations of metallicity, rotation, age, kinematics, and
Galactic orbits for a complete, magnitude-limited, and kinematically unbiased sample of 16 …

Various effective temperature scales have been proposed over the years. Despite much
work and the high internal precision usually achieved, systematic differences of order 100 K …

We report on the results of the Sun in Time multiwavelength program (X-rays to UV) of solar
analogs with ages covering∼ 0.1–7 Gyr. The chief science goals are to study the solar …

Context. The primordial nature of the Spite plateau is at odds with the WMAP satellite
measurements, implying a primordial Li production at least three times higher than …

▪ Abstract The information on the chemical compositions of stars encoded in their spectra
plays a central role in contemporary astrophysics. Stellar element abundances are …

Context. The effective temperature scale of FGK stars, especially at the lowest metallicities
remains a major problem in the chemical abundance analysis of metal-poor stars. Aims. We …

Very high quality spectra of 24 metal-poor halo dwarfs and subgiants have been acquired
with ESO's VLT/UVES for the purpose of determining Li isotopic abundances. The derived …
