The Massive Runaway Stars HD 14633 and HD 15137
T. S. Boyajian, T. D. Beaulieu, D. R. Gies +6
We present results from a radial velocity study of two runaway O-type stars, HD 14633 (ON8.5 V) and HD 15137 (O9.5 III(n)). We find that HD 14633 is a single-lined spectroscopic bi…
A Spectroscopic study of the non-thermal radio emitter Cyg OB2 #8A: Discovery of a new binary system
M. De Becker, G. Rauw, J. Manfroid
We present the results of a spectroscopic campaign revealing that the non-thermal radio emitter Cyg OB2 #8A is an O6 + O5.5 binary system. We propose the very first orbital solutio…
On the multiplicity of the O-star Cyg OB2 #8A and its contribution to the gamma-ray source 3EG J2033+4118
M. De Becker, G. Rauw, J. -P. Swings
We present the results of an intensive spectroscopic campaign in the optical waveband revealing that Cyg OB2 #8A is an O6 + O5.5 binary system with a period of about 21.9 d. Cyg OB…
Quasi-simultaneous XMM-Newton and VLA observation of the non-thermal radio emitter HD\168112 (O5.5III(f^+))
M. De Becker, G. Rauw, R. Blomme +8
We report the results of a multiwavelength study of the non-thermal radio emitter HD168112 (O5.5III(f^+)). The detailed analysis of two quasi-simultaneous XMM-Newton and VLA observ…
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…
HD108: the mystery deepens with XMM-Newton observations
Y. Naze, G. Rauw, J. M. Vreux +1
In 2001, using a large spectroscopic dataset from an extensive monitoring campaign, we discovered that the peculiar Of star HD108 displayed spectacular line variations. This strang…
