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…
The mysterious sdO X-ray binary BD+37 442
U. Heber, S. Geier, A. Irrgang +4
Pulsed X-ray emission in the luminous, helium-rich sdO BD+37 442 has recently been discovered (La Palombara et al., 2012). It was suggested that the sdO star has a neutron star or…
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…
New and revised parameters for several southern OB binaries
Pavel Mayer, Horst Drechsel, Andreas Irrgang
Using ESO FEROS archive spectra of several southern OB-type binaries, we derived periods for three SB2 spectroscopic binaries, HD 97166, HD 115455, and HD 123590, and two SB1 syste…
