title = "Colliding wind binaries and γ-ray binaries: Relativistic version of the RAMSES code",
abstract = "γ-ray binaries are colliding wind binaries (CWB) composed of a massive star a nonaccreting pulsar with a highly relativistic wind. Particle acceleration at the shocks results in emission going from extended radio emission to the γ-ray band. The interaction region is expected to show common features with stellar CWB. Performing numerical simulations with the hydrodynamical code RAMSES, we focus on their structure and stability and find that the Kelvin-Helmholtz instability (KHI) can lead to important mixing between the winds and destroy the large scale spiral structure. To investigate the impact of the relativistic nature of the pulsar wind, we extend RAMSES to relativistic hydrodynamics (RHD). Preliminary simulations of the interaction between a pulsar wind and a stellar wind show important similarities with stellar colliding winds with small relativistic corrections.",
