Description
The Sloan Digital Sky Survey (SDSS) started a new phase in 2008 August,
with new instrumentation and new surveys focused on Galactic structure
and chemical evolution, measurements of the baryon oscillation feature
in the clustering of galaxies and the quasar Lyα forest, and a
radial velocity search for planets around ~8000 stars. This paper
describes the first data release of SDSS-III (and the eighth counting
from the beginning of the SDSS). The release includes five-band imaging
of roughly 5200 deg2 in the southern Galactic cap, bringing
the total footprint of the SDSS imaging to 14,555 deg2, or
over a third of the Celestial Sphere. All the imaging data have been
reprocessed with an improved sky-subtraction algorithm and a final,
self-consistent photometric recalibration and flat-field determination.
This release also includes all data from the second phase of the Sloan
Extension for Galactic Understanding and Exploration (SEGUE-2),
consisting of spectroscopy of approximately 118,000 stars at both high
and low Galactic latitudes. All the more than half a million stellar
spectra obtained with the SDSS spectrograph have been reprocessed
through an improved stellar parameter pipeline, which has better
determination of metallicity for high-metallicity stars.

Observational Tests of the Processes of Nucleosynthesis in the Universe
Several spectroscopic analyses of stars with planets have recently been carried out. One of the most remarkable results is that planet-harbouring stars are on average more metal-rich than solar-type disc stars. Two main explanations have been suggested to link this metallicity excess with the presence of planets. The first of these, the “self

Chemical Abundances in Stars
Stellar spectroscopy allows us to determine the properties and chemical compositions of stars. From this information for stars of different ages in the Milky Way, it is possible to reconstruct the chemical evolution of the Galaxy, as well as the origin of the elements heavier than boron, created mainly in stellar interiors. It is also possible to
