- Descripción
- 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).
Las estrellas de gran masa despiden vientos supersónicos con una enorme potencia cinética capaces de acelerar partículas relativistas. Dichas partículas pueden emitir radiación no térmica a lo largo de todo el espectro electromagnético. Aquí presentamos un resumen de nuestras investigaciones de la emisión no térmica producida en sistemas con estrellas de gran masa (burbujas estelares, bow shocks, binarias con colisión de vientos y microcuásares). Nuestro objetivo central es determinar la eficiencia de aceleración de rayos cósmicos en estos sistemas, bajo qué condiciones son capaces de ser emisores no térmicos y las características de sus campos magnéticos. Enfatizamos la relevancia del desarrollo de modelos radiativos y su retroalimentación positiva con campañas observacionales multi-frecuencia desde ondas de radio hasta altas energías (rayos X y rayos 7).
