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…
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…
A new extragalactic distance determination method using the flux-weighted gravity of late B and early A supergiants
Rolf P. Kudritzki, Fabio Bresolin, Norbert Przybilla
Stellar evolution calculations predict the flux-weighted gravity g/Teff^4 and absolute bolometric magnitude of blue supergiants to be strongly correlated. We use medium resolution…
