The most luminous stars in the Galaxy and the Magellanic Clouds
Wolf-Rainer Hamann, Andreas Barniske, Adriane Liermann +3
Some of the Wolf-Rayet stars are found to have very high bolometric luminosities (more than 1000000 solar). We employ the Potsdam Wolf-Rayet (PoWR) model atmospheres for their spec…
The Quintuplet Cluster II. Analysis of the WN stars
A. Liermann, W. -R. Hamann, L. M. Oskinova +2
Based on -band integral-field spectroscopy, we analyze four Wolf-Rayet stars of the nitrogen sequence (WN) found in the inner part of the Quintuplet cluster. All WN stars (WR102…
The Quintuplet Cluster I. A K-band spectral catalog of stellar sources
A. Liermann, W. -R. Hamann, L. M. Oskinova
Three very massive clusters are known to reside in the Galactic Center region, the Arches cluster, the Quintuplet cluster and the Central parsec cluster. We obtained spectroscopic…
The Galactic WN stars: Spectral analyses with line-blanketed model atmospheres versus stellar evolution models with and without rotation
W. -R. Hamann, G. Graefener, A. Liermann
CONTEXT: Very massive stars pass through the Wolf-Rayet (WR) stage before they finally explode. Details of their evolution have not yet been safely established, and their physics a…
