« Gamma-ray binaries: shining a light on pulsars »

Gamma-ray binaries are systems composed of a massive star and a compact object, most likely a young rotation-powered pulsar. The interaction between the pulsar wind and the stellar wind of the companion is at the origin of highly-efficient particle acceleration. Light from the massive star shines on these particles, producing copious gamma-ray emission modulated on the orbital period, and providing us with a unique probe of the pulsar wind. I will present what we have learned from these systems and the challenges they pose to our understanding of pulsars.
