On the photometric variability of blue supergiants in NGC 300 and its impact on the Flux-weighted Gravity-Luminosity Relationship
Fabio Bresolin, Grzegorz Pietrzynski, Wolfgang Gieren +3
We present a study of the photometric variability of spectroscopically confirmed supergiants in NGC 300, comprising 28 epochs extending over a period of five months. We find 15 cle…
The Chemical Composition of Two Supergiants in the Dwarf Irregular Galaxy WLM
K. A. Venn, E. Tolstoy, A. Kaufer +5
[Abridged] The chemical composition of two stars in WLM has been determined from high quality UVES data obtained at the VLT UT2 (program 65.N-0375). The model atmospheres analysis…
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…
Quantitative spectral analysis of early B-type supergiants in the Sculptor galaxy NGC 300
Miguel Alejandro Urbaneja, Artemio Herrero, Fabio Bresolin +3
The spectra of two early B-type supergiant stars in the Sculptor spiral galaxy NGC 300 are analysed by means of non-LTE line blanketed unified model atmospheres, aimed at determini…
