Numerical simulations of the collision of an inhomogeneous stellar wind and a relativistic pulsar wind in a binary system
Binary systems hosting a massive star and a non-accreting pulsar present strong interacting winds. The stellar wind can be clumpy resulting in an unstable two-wind interaction region, which can strongly influence the non-thermal emission of the binary system. We performed axisymmetric relativistic h...

Binary systems hosting a massive star and a non-accreting pulsar present strong interacting winds. The stellar wind can be clumpy resulting in an unstable two-wind interaction region, which can strongly influence the non-thermal emission of the binary system. We performed axisymmetric relativistic hydrodynamical simulations of the interaction between a relativistic pulsar wind (Lorentz factors up to 6) and an inhomogeneous stellar wind with different degrees of inhomogeneity. The simulations show that the stellar wind inhomogeneities can significantly reduce the two-wind interaction region size. In addition, the whole interaction region is quite unstable, and presents a complex spatial and temporal pattern, with the shocked pulsar wind structure strongly changing under small perturbations. All of this can lead to strong variations in the non-thermal output from these binary systems. |
