A non-LTE spectral analysis of the 3He and 4He isotopes in the HgMn star kappa Cancri
Natalia L. Maza, Maria-Fernanda Nieva, Norbert Przybilla
We present a pilot study on non-local thermodynamic equilibrium (NLTE) line-formation computations for the isotopes 3He and 4He in the mercury-manganese star kappa Cancri. The impa…
Fundamental properties of nearby single early B-type stars
Maria-Fernanda Nieva, Norbert Przybilla
Fundamental parameters of a sample of 26 apparently slowly-rotating single early B-type stars in the solar neighbourhood are presented and compared to high-precision data from deta…
B fields in OB stars (BOB): on the detection of weak magnetic fields in the two early B-type stars beta CMa and epsilon CMa
L. Fossati, N. Castro, T. Morel +15
Within the context of the "B fields in OB stars (BOB)" collaboration, we used the HARPSpol spectropolarimeter to observe the early B-type stars beta CMa (HD44743; B1 II/III) and ep…
The B Fields in OB Stars (BOB) Survey
T. Morel, N. Castro, L. Fossati +29
The B fields in OB stars (BOB) survey is an ESO large programme collecting spectropolarimetric observations for a large number of early-type stars in order to study the occurrence…
Stellar Metallicity of the Extended Disk and Distance of the Spiral Galaxy NGC 3621
Rolf-Peter Kudritzki, Miguel A. Urbaneja, Fabio Bresolin +2
Low resolution ESO VLT/FORS spectra of blue supergiant stars are analyzed to determine stellar metallicities (based on elements such as Fe, Ti, Mg) in the extended disk of the spir…
A new method for an objective, -based spectroscopic analysis of early-type stars
Andreas Irrgang, Norbert Przybilla, Ulrich Heber +4
A precise quantitative spectral analysis - encompassing atmospheric parameter and chemical elemental abundance determination - is time consuming due to its iterative nature and the…
