Three-dimensional orbits of the triple-O stellar system HD 150136
H. Sana, J. -B. Le Bouquin, L. Mahy +3
Context. HD 150136 is a triple hierarchical system and a non-thermal radio emitter. It is formed by an O3-3.5 V + O5.5-6 V close binary and a more distant O6.5-7 V tertiary. So far…
The non-thermal radio emitter HD 93250 resolved by long baseline interferometry
H. Sana, J. -B. Le Bouquin, M. De Becker +3
As the brightest O-type X-ray source in the Carina nebula, HD 93250 (O4 III(fc)) is X-ray overluminous for its spectral type and has an unusually hard X-ray spectrum. Two different…
X-shooter, NACO, and AMBER observations of the LBV Pistol Star \footnote{Based on ESO runs 85.D-0182A, 085.D-0625AC}
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
We present multi-instruments and multi-wavelengths observations of the famous LBV star Pistol Star. These observations are part of a larger program about early O stars at different…
A new investigation of the binary HD 48099
L. Mahy, G. Rauw, F. Martins +5
With an orbital period of about 3.078 days, the double-lined spectroscopic binary HD 48099 is, still now, the only short-period O+O system known in the Mon OB2 association. Even th…
The massive binary HD 152218 revisited: A new colliding wind system in NGC 6231
H. Sana, Y. Nazé, B. O'Donnell +2
We present the results of an optical and X-ray monitoring campaign on the short-period massive SB2 binary HD 152218. Combining our HiRes spectroscopic data with previous observatio…
The investigation of particle acceleration in colliding-wind massive binaries with SIMBOL-X
M. De Becker, G. Rauw, J. M. Pittard +4
An increasing number of early-type (O and Wolf-Rayet) colliding wind binaries (CWBs) is known to accelerate particles up to relativistic energies. In this context, non-thermal emis…
