A multiwavelength investigation of the massive eclipsing binary Cyg OB2 #5
N. Linder, G. Rauw, J. Manfroid +5
The properties of the early-type binary Cyg OB2 #5 have been debated for many years and spectroscopic and photometric investigations yielded conflicting results. We have attempted…
High resolution optical spectroscopy of Plaskett's star
N. Linder, G. Rauw, F. Martins +3
We present here the analysis of an extensive set of high resolution optical spectra of Plaskett's star (HD 47129). We use a disentangling method to separate the individual spectra…
Spectroscopic and photometric variability of the O9.5Vp star HD93521
G. Rauw, M. De Becker, H. van Winckel +7
The line profile variability and photometric variability of the O9.5 Vp star HD93521 are examined in order to establish the properties of the non-radial pulsations in this star. Fo…
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…
The massive star binary fraction in young open clusters I. NGC 6231 revisited
H. Sana, E. Gosset, Y. Naze +2
We present the results of a long-term high-resolution spectroscopy campaign on the O-type stars in NGC 6231. We revise the spectral classification and multiplicity of these objects…
