Testing the theory of colliding winds: The periastron passage of 9 Sagittarii. II. Radio monitoring
R. Blomme, G. Rauw, D. Volpi +3
Colliding winds in massive-star binaries generate non-thermal radio emission and an increased X-ray emission. We study the radio emission of the non-thermal emitter 9 Sgr, which is…

X-raying the wind-wind collisions in HD 168112 and HD 167971
Gregor Rauw, Ronny Blomme, Yaël Nazé +1
The O-type long-period binary HD 168112 and triple HD 167971 star systems have been known for several decades for their non-thermal synchrotron radio emission. This emission arises…
