Equatorial outflows driven by jets in Population III microquasars

Binary systems of Population III can evolve to microquasars when one the stars collapses into a black hole. When compact object accretes matter at rate greater than Eddington rate, powerful jets and winds driven by strong radiation pressure should form. We investigate structure jet-wind system for model microquasar on scales beyond formation region. Using relativistic hydrodynamic simulations we find that ratio kinetic power between jet disk wind determines configuration system. is dominated wind, fills narrow channel, collimated dense outflow. dominates system, part its energy diverted turning quasi-equatorial flow, while widens.
