Non-thermal emission from secondary pairs in close TeV binary systems

Abstract

Context. Massive hot stars produce dense ultraviolet (UV) photon fields in their surroundings. If a very high-energy (VHE) gammaray emitter is located close to the star, then gamma-rays are absorbed in the stellar photon field, creating secondary (electron-positron) pairs. Aims. We study the broadband emission of these secondary pairs in the stellar photon… (More)
