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…
A binary signature in the non-thermal radio-emitter Cyg OB2 #9
Y. Naze, M. De Becker, G. Rauw +1
Aims: Non-thermal radio emission associated with massive stars is believed to arise from a wind-wind collision in a binary system. However, the evidence of binarity is still lackin…
Early-type stars in the core of the young open cluster Westerlund2
G. Rauw, J. Manfroid, E. Gosset +5
Aims. The properties of the early-type stars in the core of the Westerlund2 cluster are examined in order to establish a link between the cluster and the very massive Wolf-Rayet bi…
Non-thermal radio emission from O-type stars. I. HD 168112
R. Blomme, S. Van Loo, M. De Becker +4
We present a radio lightcurve of the O5.5 III(f+) star HD 168112, based on archive data from the Very Large Array (VLA) and the Australia Telescope Compact Array (ATCA). The fluxes…
An XMM-Newton observation of the massive binary HD159176
M. De Becker, G. Rauw, J. M. Pittard +4
We report the analysis of an XMM-Newton observation of the close binary HD159176 (O7V + O7V). The observed L_X/L_bol ratio reveals an X-ray luminosity exceeding by a factor ~ 7 the…
