The Struve-Sahade effect in the optical spectra of O-type binaries I. Main-sequence systems
N. Linder, G. Rauw, H. Sana +2
We present a spectroscopic analysis of four massive binary systems that are known or are good candidates to display the Struve-Sahade effect (defined as the apparent strengthening…
An XMM-Newton view of the young open cluster NGC 6231 -- I. The catalogue
H. Sana, E. Gosset, G. Rauw +2
This paper is the first of a series dedicated to the X-ray properties of the young open cluster NGC 6231. Our data set relies on an XMM-Newton campaign of a nominal duration of 180…
CPD-41deg7742: an unusual wind interaction
H. Sana, E. Gosset, G. Rauw +4
We summarize the results of a multiwavelength observing campaign on the massive eclipsing binary CPD-41deg7742, another remarkable object in the young open cluster NGC 6231. Our ca…
Optical spectroscopy of X-Mega targets in the Carina Nebula - V. The spectroscopic binary HD93161A and its visual companion HD93161B
Y. Naze, I. I. Antokhin, H. Sana +2
We present the analysis of an extensive set of high resolution spectroscopic observations of HD93161, a visual binary with a separation of 2 arcsec. HD93161 A is a spectroscopic bi…
WR20a: a massive cornerstone binary system comprising two extreme early-type stars
G. Rauw, M. De Becker, Y. Naze +6
We analyse spectroscopic observations of WR20a revealing that this star is a massive early-type binary system with a most probable orbital period of \sim 3.675 days. Our spectra in…
A phase-resolved XMM-Newton Campaign on the Colliding Wind Binary HD 152248
H. Sana, I. R. Stevens, E. Gosset +2
We report the first results of an XMM-Newton monitoring campaign of the NGC 6231 open cluster in the Sco OB1 association. This first paper focuses on the massive colliding wind bin…
