Non-thermal radio emission from colliding-wind binaries: modelling Cyg OB2 No. 8A and No. 9
Delia Volpi, Ronny Blomme, Michael De Becker +1
Some OB stars show variable non-thermal radio emission. The non-thermal emission is due to synchrotron radiation that is emitted by electrons accelerated to high energies. The elec…
HD 259440: The Proposed Optical Counterpart of the gamma-ray Binary HESS J0632+057
Christina Aragona, M. Virginia McSwain, Michael De Becker
HD 259440 is a B0pe star that was proposed as the optical counterpart to the gamma-ray source HESS J0632+057. Here we present optical spectra of HD 259440 acquired to investigate t…
Non-thermal radio emission from O-type stars. IV. Cyg OB2 No. 8A
R. Blomme, M. De Becker, D. Volpi +1
We study the non-thermal radio emission of the binary Cyg OB2 No. 8A, to see if it is variable and if that variability is locked to the orbital phase. We investigate if the synchro…
First orbital solution for the non-thermal emitter Cyg OB2 #9
Y. Naze, Y. Damerdji, G. Rauw +7
After the first detection of its binary nature, the spectroscopic monitoring of the non-thermal radio emitter Cyg OB2 #9 (P=2.4yrs) has continued, doubling the number of available…
New findings on the prototypical Of?p stars
Y. Naze, A. ud-Doula, M. Spano +3
In recent years several in-depth investigations of the three Galactic Of?p stars were undertaken. These multiwavelength studies revealed the peculiar properties of these objects (i…
A photometric and spectroscopic investigation of star formation in the very young open cluster NGC6383
G. Rauw, J. Manfroid, M. De Becker
The very young open cluster NGC 6383 centered on the O-star binary HD 159176 is an interesting place for studying the impact of early-type stars with strong radiation fields and po…
