Long baseline interferometry as a tool to investigate colliding-wind massive binaries

Massive stars present the interesting property to generate strong
stellar winds. In the particular case of binary systems made of two
massive stars, the two stellar winds are likely to collide. In addition,
in this scenario, interesting physics is occurring, such as strong
high-energy emission, dust production or even particle acceleration.
However, our capability to understand these "higher-level" processes
relies intimately on our knowledge of stellar and orbital parameters of
these binaries, and on our vision of the hydrodynamics that is taking
place in these objects. In this context, the purpose of this
presentation is to discuss the expected contribution of long baseline
interferometry.
