VizieR Online Data Catalog: Nearby B-stars stellar parameters and abundances (Nieva+, 2012)
Abstract
Stellar parameters and elemental abundances for a sample of 20 sharp-lined early B-type stars in the solar vicinity are presented. High-resolution and high-S/N FOCES, FEROS and ELODIE spectra were investigated using sophisticated non-LTE modelling and a comprehensive analysis methodology. Independent indicators like multiple ionization equilibria, the Stark-broadened hydrogen Balmer line profiles and large numbers of helium and metal lines were reproduced simultaneously. Precise and accurate data on effective temperatures, surface gravities, microturbulent, macroturbulent and projected rotational velocities, color excesses, intrinsic V magnitudes, evolutionary masses, spectroscopic distances and distances from Hipparcos parallaxes, and elemental abundances for carbon, nitrogen, oxygen, neon, magnesium, silicon and iron are summarised in the tables.
