Constraints on the Production Mechanism of TeV γ-Rays in X-Ray Binaries

  • Paul A. Johnson
Part of the NATO ASI Series book series (ASIC, volume 270)


The absorption of TeV γ-rays by pair-production in the HZ Her/Her X-l binary system and its implication for production mechanisms is investigated. One of the absorption regions, the accretion disk corona, causes very strong attenuation of TeV γ-rays produced near to its centre, and suggests that a more likely method for their creation would be the dumping of a proton beam into some outlying matter, such as the rim of the accretion disk.
