The very massive X-ray bright binary system Wack 2134 (= WR 21a)
V. S. Niemela, R. C. Gamen, R. H. Barba +5
From the radial velocities of the N IV 4058 and He II 4686 emission lines, and the N V 4604-20 absorption lines, determined in digital spectra, we report the discovery that the X-r…
Using gamma-rays to probe the clumped structure of stellar winds
G. E. Romero, S. P. Owocki, A. T. Araudo +2
Gamma-rays can be produced by the interaction of a relativistic jet and the matter of the stellar wind in the subclass of massive X-ray binaries known as "microquasars". The relati…
Testing the predicted mass-loss bi-stability jump at radio wavelengths
P. Benaglia, J. S. Vink, J. Marti +3
In this study, we test the theoretically predicted mass-loss behaviour as a function of stellar effective temperature across the so-called `bi-stability' jump (BSJ). We gathered ra…
The stellar upper mass limit in the solar neighborhood
J. Maíz Apellániz, Nolan R. Walborn, N. I. Morrell +4
We are using HST GO programs 10205, 10602, and 10898 to test the stellar upper mass limit in the solar vicinity by attempting to detect optical close companions, thus lowering the…
XMM detection of the supernova remnant G337.2+0.1
Jorge A. Combi, Juan F. Albacete Colombo, Gustavo E. Romero +1
We report the first XMM detection of the SNR candidate G337.2+0.1 (=AX J1635.9-4719). The object shows centrally filled and diffuse X-ray emission. The emission peaks in the hard 3…
Radio evidence on the mass loss bi-stability jump
P. Benaglia, J. S. Vink, J. Marti +3
We present the results of a first campaign of radio continuum observations toward supergiants with spectral types in the range O8 - B3. Three targets out of twelve were detected wi…
