Aims. HD 96446 is a magnetic B2p He-strong star that has been reported to be a β Cep pulsator. We present a detailed spectroscopic analysis of this object based on an intensive observational data set obtained in a multisite campaign with the spectro

Hot stars and cosmic abundances
Autor: Norbert Przybilla, Andreas Irrgang, Keith Butler, M.-F. Nieva
Publikováno v: EAS Publications Series. 63:13-23
Hot massive stars are ideal indicators for present-day cosmic abundances. We review results from a non-LTE study of a larger sample of early B-type stars in the solar neighbourhood by Nieva & Przybilla (2012) and extend the analysis. Using comprehens

Temperature and gravity scales in hot stars
Autor: M.-F. Nieva
Publikováno v: EAS Publications Series. 64:47-54
Precise determinations of effective temperatures and surface gravities are mandatory to derive not only reliable chemical abundances, but also parameters like distances, masses, radii and luminosities in OB stars. We have previously determined atmosp

Quantitative spectroscopy of OB stars: from dwarfs to supergiants
Autor: M.-F. Nieva, M. Firnstein, Keith Butler, Norbert Przybilla
Publikováno v: EAS Publications Series. 64:37-45
We discuss recent progress made in the spectral modelling of OB stars from the main sequence to evolved phases as BA-type supergiants. Non-LTE line-formation computations can now reproduce observed spectra over the entire optical and near-IR waveleng

Publikováno v: Astronomy & Astrophysics. 618:L2
We focus on early-B type stars with helium overabundance, for which the presence of a magnetic field has not previously been reported. The measurements were carried out using high-spectral-resolution spectropolarimetric observations obtained with the
