Foreground and internal free-free absorption in particle-accelerating colliding-wind binaries : Insights from the radio emission of WR 147
M. Tasseroul, M. De Becker, A. B Blanco +2
Radio emission from massive binary systems is generally of composite nature, showing both a thermal emission component from the winds and a non-thermal component from relativistic…

Radio study of the colliding wind binary HD93129A near periastron and its surroundings
Paula Benaglia, Santiago del Palacio, Juliana Saponara +3
HD93129A is an O+O stellar system whose CWR has been mapped by high angular resolution observations at cm wavelengths. The synchrotron nature of the radio emission confirms its par…

Insight into the occurrence of particle acceleration through the investigation of Wolf-Rayet stars using uGMRT observations
A. B. Blanco, M. De Becker, A. Saha +2
Massive stars produce strong stellar winds that consist of continuous outflows of material at speeds of thousands of km/s. These winds convey large amounts of kinetic power, especi…
