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…
An XMM-Newton view of the young open cluster NGC 6231 III. Optically faint X-ray sources
H. Sana, G. Rauw, H. Sung +2
We discuss the properties of the X-ray sources with faint optical counterparts in the very young open cluster NGC 6231. From their positions in the H-R diagram, we find that the bu…
Constraining the fundamental parameters of the O-type binary CPD-41degr7733
H. Sana, G. Rauw, E. Gosset
Using a set of high-resolution spectra, we studied the physical and orbital properties of the O-type binary CPD-41 7733, located in the core of \ngc. We report the unambiguous dete…
An XMM-Newton view of the young open cluster NGC 6231 -- II. The OB star population
H. Sana, G. Rauw, Y. Naze +2
In this second paper, we pursue the analysis of the 180 ks XMM-Newton campaign towards the young open cluster NGC 6231 and we focus on its rich OB star population. We present a lit…
An exceptional X-ray view of the young open cluster NGC 6231: what XMM-Newton has taught us
H. Sana, E. Gosset, G. Rauw +1
Considered as the core of the Sco OB1 association, the young open cluster NGC 6231 harbours a rich O-type star population. In 2001, the XMM-Newton satellite targeted the cluster fo…
