We review the current status of our knowledge of the chemical composition of the Sun,
essentially derived from the analysis of the solar photospheric spectrum. The comparison of …

Abstract Forty years ago Burbidge, Burbidge, Fowler, and Hoyle combined what we would
now call fragmentary evidence from nuclear physics, stellar evolution and the abundances …

Solar photospheric and meteoritic CI chondrite abundance determinations for all elements
are summarized and the best currently available photospheric abundances are selected …

The first serious attempt to establish a comprehensive list of “cosmic abundances” was
made by the geochemist Victor Moritz Goldschmidt. During the 20s and 30s of the last …

Context. The chemical composition of the Sun is a fundamental yardstick in astronomy,
relative to which essentially all cosmic objects are referenced. As such, having accurate …

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 …

Neutral sodium is a minority species in the atmospheres of late-type stars, and line formation
in local thermodynamic equilibrium (LTE) is often a poor assumption, in particular for strong …

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 …

We report on the discovery of WASP-12b, a new transiting extrasolar planet with R pl= 1.79+
0.09− 0.09 RJ and M pl= 1.41+ 0.10− 0.10 M J. The planet and host star properties were …
