The VLT-FLAMES Tarantula Survey XIX. B-type Supergiants - Atmospheric parameters and nitrogen abundances to investigate the role of binarity and the width of the main sequence
C. M. McEvoy, P. L. Dufton, C. J. Evans +19
TLUSTY non-LTE model atmosphere calculations have been used to determine atmospheric parameters and nitrogen (N) abundances for 34 single and 18 binary B-type supergiants (BSGs). T…
Orbital and physical properties of the Ori Aa,Ab,B triple system
Simón-Díaz, J. A. Caballero, J. Lorenzo +11
We provide a complete characterization of the astrophysical properties of the Ori Aa,Ab,B hierarchical triple system, and an improved set of orbital parameters for the highly e…
The occurrence of classical Cepheids in binary systems
Hilding R. Neilson, Fabian R. N. Schneider, Robert G. Izzard +2
Classical Cepheids, like binary stars, are laboratories for stellar evolution and Cepheids in binary systems are especially powerful ones. About one-third of Galactic Cepheids are…
The spectroscopic Hertzsprung-Russell diagram of Galactic massive stars
N. Castro, L. Fossati, N. Langer +3
The distribution of stars in the Hertzsprung-Russell diagram narrates their evolutionary history and directly assesses their properties. Placing stars in this diagram however requi…
Numerical Tests of Rotational Mixing in Massive Stars with the new Population Synthesis Code BONNFIRES
Herbert H. B. Lau, Robert G. Izzard, Fabian R. N. Schneider
We use our new population synthesis code BONNFIRES to test how surface abundances predicted by rotating stellar models depend on the numerical treatment of rotational mixing, such…
BONNSAI: a Bayesian tool for comparing stars with stellar evolution models
Fabian R. N. Schneider, Norbert Langer, Alex de Koter +3
Powerful telescopes equipped with multi-fibre or integral field spectrographs combined with detailed models of stellar atmospheres and automated fitting techniques allow for the an…
