Description

Synchrotron radiation identified in the radio domain for several tens of binary systems made of massive stars provides compelling evidence that a particle acceleration process is at work in these objects, hence their Particle-Accelerating Colliding-Wind Binaries (PACWB) status. Measurements of the synchrotron radio emission allow to investigate the non-thermal physics and to derive some of their properties. In this context, it is worth investigating the expectations from longer wavelengths such as those measured by the Giant Metrewave Radio Telescope (GMRT) in India, in complementarity with the most abundant measurements at centimetric wavelengths obtained with other radio observatories such as the Very Large Array (VLA) or the Australia Telescope Compact Array (ATCA). This talk will outline such expectations and address the issue of the underlying physics in its appropriate context.
