Extragalactic Stellar Astronomy with Blue Supergiants
N. Przybilla, F. Bresolin, K. Butler +3
The present generation of large telescopes facilitates spectroscopy of blue supergiants in galaxies out to distances beyond the Local Group. Recent developments in NLTE spectrum sy…
Stellar Abundances in Dwarf Irregular Galaxies
Kim Venn, Eline Tolstoy, Andreas Kaufer +1
Dwarf irregular galaxies appear to have undergone very slow chemical evolution since they have low nebular abundances, but have had ongoing star formation over the past 15 Gyr. The…
New Nitrogen and Carbon in AF-supergiants
Kim A. Venn, Norbert Przybilla
The AF-supergiants in the Galaxy and the SMC allow us to examine predictions from evolution models through their CNO abundances. In these proceedings, we recalculate the NLTE nitro…
The Wind Momentum - Luminosity Relationship of Galactic A- and B- Supergiants
R. P. Kudritzki, J. Puls, D. J. Lennon +5
The Balmer lines of four A Ia - supergiants (spectral type A0 to A3) and fourteen B Ia and Ib - supergiants (spectral type B0 to B3) in the solar neighbourhood are analyzed by mean…
The Abundance of Boron in Evolved A- and B-Type Stars
Kim A. Venn, David L. Lambert, Michael Lemke
Boron abundances in A- and B-type stars may be a successful way to track evolutionary effects in these hot stars. The light elements -- Li, Be, and B -- are tracers of exposure to…
