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…
Stellar Winds of Hot Massive Stars Nearby and Beyond the Local Group
Fabio Bresolin, Rolf-Peter Kudritzki
Photospheric radiation momentum is efficiently transferred by absorption through metal lines to the gaseous matter in the atmospheres of massive stars, sustaining strong winds and…
Non-LTE line-formation for CNO
Norbert Przybilla, Rolf-Peter Kudritzki, Keith Butler +1
Accurate atomic data have become available in the recent past due to the demands of astrophysics and fusion research. We report on the impact of such data on non-LTE line-formation…
The Wind Momentum-Luminosity relationship: blue supergiants in the spiral galaxy NGC 300
Fabio Bresolin, Rolf-Peter Kudritzki, Wolfgang Gieren
We have carried out the wind analysis of six A-type supergiants in NGC 300. The derived Wind Momentum-Luminosity Relationship is compared with that of Galactic and M31 blue supergi…
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…
Intracluster Planetary Nebulae in the Virgo Cluster
K. C. Freeman, M. Arnaboldi, M. Capaccioli +8
We briefly describe the properties of the confirmed spectroscopic sample of intracluster planetary nebulae recently discovered in the Virgo cluster. We find 23 bonafide intracluste…
