Coupling hydrodynamics and radiation calculations for star-jet interactions in AGN

Stellar populations can contribute to the non-thermal emission of radio-loud active galactic nuclei via the interaction with the relativistic jets. The shock produced between the stellar wind and the jet can accelerate particles and produce high-energy emission. We have performed 2D axisymmetric hyd...
