Abstract: | Time dependent numerical simulation of relativistic wind interaction with interstellar medium was performed. The winds are ejected from magnetosphere of rotation powered pulsars. The particle flux in the winds is assumed to be isotropic. The energy flux is taken as strongly anisotropic in accordance with prediction of the MHD theory of the relativistic winds. The modeling has been performed for the wind magnetization in the range 3 × 10−3–10−1. The numerical solutions reproduce the most spectacular features observed in the central part of plerions: toroidal structure and jet-like features. Increase of the wind’s magnetization results in decrease of the size of the synchrotron nebula. |
