The Araucaria Project: the Local Group Galaxy WLM--Distance and metallicity from quantitative spectroscopy of blue Supergiants
M. A. Urbaneja, R. -P. Kudritzki, F. Bresolin +3
The quantitative analysis of low resolution spectra of A and B supergiants is used to determine a distance modulus of 24.99 +/- 0.10 mag (995 +/- 46 Kpc) to the Local Group galaxy…
Extragalactic Stellar Astronomy with the Brightest Stars in the Universe
R. -P. Kudritzki, M. A. Urbaneja, F. Bresolin +1
A supergiants are objects in transition from the blue to the red (and vice versa) in the uppermost HRD. They are the intrinsically brightest "normal" stars at visual light with abs…
Quantitative Spectroscopy of 24 A supergiants in the Sculptor galaxy NGC 300: Flux weighted gravity luminosity relationship, metallicity and metallicity gradient
R. -P. Kudritzki, M. A. Urbaneja, F. Bresolin +3
A quantitative spectral analysis of 24 A supergiants in the Sculptor Group spiral galaxy NGC 300 at a distance of 1.9 Mpc is presented. A new method is introduced to analyze low re…
Extragalaxtic Stellar Astronomy
Miguel A. Urbaneja, Rolf Peter Kudritzki, Fabio Bresolin
Despite their paucity, massive hot stars are real cosmic engines of fundamental importance in shaping our Universe, from its very early stages up to its current appearance. Underst…
VLT spectroscopy of blue supergiants in IC 1613
Fabio Bresolin, Miguel A. Urbaneja, Wolfgang Gieren +2
We present multi-object spectroscopy of young, massive stars in the Local Group galaxy IC 1613. We provide the spectral classification and a detailed spectral catalog for 54 OBA st…
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…
