| Sumario: | Massive stars launch powerful, supersonic winds which carry a huge kinetic power. These can generate strong shocks capable of accelerating relativistic particles. Such particles can emit broadband nonthermal radiation. Here we present an overview of the investigations we carried out focused on the non-thermal emission produced in systems involving massive stars (stellar bubbles, stellar bow shocks, colliding-wind binaries, and microquasars). Our main goal is to determine the cosmic-ray acceleration efficiency in these systems, the conditions upon which they can become non-thermal emitters, and the characteristics of their magnetic fields. We highlight the importance of developing broadband radiation models and their virtuous feedback with multifrequency observational campaigns comprising from radio wavelengths up to high energies (X-rays and 7 rays). |
