Non-Thermal Radio Emission from Colliding-Wind Binaries (2009)
In colliding-wind binaries, shocks accelerate a fraction of the electrons up to relativistic speeds. These electrons then emit synchrotron radiation at radio wavelengths. Whether or not we detect...
De Becker, M., Blomme, R., Micela, G., Pittard, J. M., Rauw, G., Romero, G. E., ...
Several colliding-wind massive binaries are known to be non-thermal emitters in the radio domain. This constitutes strong evidence for the fact that an efficient particle acceleration process is at...
Non-Radial Pulsations and Large-Scale Structure in Stellar Winds (2009)
Almost all early-type stars show Discrete Absorption Components (DACs) in their ultraviolet spectral lines. These can be attributed to Co-rotating Interaction Regions (CIRs): large-scale...
The Gaia satellite: a tool for Emission Line Stars and Hot Stars (2008)
Martayan, C, Frémat, Y, Blomme, R, Jonckheere, A, Borges, M, De Batz, B, ...
The Gaia satellite will be launched at the end of 2011. It will observe at least 1 billion stars, and among them several million emission line stars and hot stars. Gaia will provide parallaxes for...
The investigation of particle acceleration in colliding-wind massive binaries with SIMBOL-X. (2008)
De Becker, Michaël, Rauw, Grégor, Pittard, J M, Blomme, R, Romero, G E, Sana, H, ...
An increasing number of early-type (O and Wolf-Rayet) colliding wind binaries (CWBs) is known to accelerate particles up to relativistic energies. In this context, non-thermal emission processes such...
The Infrared and Radio Continuum of Early-Type Stars (2007)
Runacres And, M. C. Runacres, R. Blomme
. The infrared and radio continuum fluxes of 18 well-observed early-type stars are studied by comparing observations with theoretical models. The observations are taken from the literature. All...
The Influence of Clumping on the Infrared and Radio Continuum of Early-Type Stars (2007)
Blomme And, R. Blomme, M. C. Runacres
. Time-dependent hydrodynamical models predict that the stellar winds of early-type stars are clumped, due to the sweeping up of material into dense shells. In this paper we investigate whether these...
A multi-wavelength investigation of the non-thermal radio emitting O-star 9 Sgr (2002)
Rauw, Grégor, Blomme, R, Waldron, WL, Corcoran, MF, Pittard, JM, Pollock, AMT, ...
We report the results of a multi-wavelength investigation of the O4 V star 9 Sgr (= HD164794). Our data include observations in the X-ray domain with XMM-Newton, in the radio domain with the VLA as...
