The Wolf-Rayet stars in the Large Magellanic Cloud: A comprehensive analysis of the WN class
R. Hainich, U. Rühling, H. Todt +6
Aims: Following our comprehensive studies of the WR stars in the Milky Way, we now present spectroscopic analyses of almost all known WN stars in the LMC. Methods: For the quantita…
A 10-hour period revealed in optical spectra of the highly variable WN8 Wolf-Rayet star WR 123
A. -N. Chené, C. Foellmi, S. V. Marchenko +6
Aims. What is the origin of the large-amplitude variability in Wolf-Rayet WN8 stars in general and WR123 in particular? A dedicated spectroscopic campaign targets the ten-hour peri…
A brown dwarf companion to the intermediate-mass star HR6037
N. Huelamo, D. E. A. Nuernberger, V. D. Ivanov +8
In the course of an imaging survey we have detected a visual companion to the intermediate-mass star HR 6037. In this letter, we present two epoch observations of the binary with N…
The pertinence of Jet Emitting Discs physics to Microquasars: Application to Cygnus X-1
P. O. Petrucci, J. Ferreira, G. Henri +2
The interpretation of the X-ray spectra of X-ray binaries during their hard states requires a hot, optically thin medium. There are several accretion disc models in the literature…
What is the closest black hole to the Sun?
C. Foellmi
We examine the distance of the two galactic microquasars GRO J1655-40 and A0620-00, which are potentially the two closest black holes to the Sun. We aim to provide a picture as wid…
Properties of WNh stars in the Small Magellanic Cloud: evidence for homogeneous evolution
F. Martins, D. J. Hillier, J. C. Bouret +4
We derive the physical properties of three WNh stars in the SMC to constrain stellar evolution beyond the main sequence at low metallicity and to investigate the metallicity depend…
