Present-day cosmic abundances. A comprehensive study of nearby early B-type stars and implications for stellar and Galactic evolution and interstellar dust models.

This article presents a careful abundance analysis of a sample of local early-type B stars. New improved atomic data and a homogeneous analysis of high-quality spectra yields results with much more reduced scatter than in previous investigations of samples of comparable size. This is an important step into establishing the present-day cosmic abundance standard.
