摘要
We have shown the simultaneous generation of macroscale fast flows and strong magnetic fields in the two-temperature relativistic electron-ion plasmas of astrophysical objects due to the Unified Reverse Dynamo/Dynamo mechanism. The resulting dynamical magnetic-field amplification and/or flow acceleration is directly proportional to the initial turbulent kinetic/magnetic (magnetic) energy; the process is very sensitive to the relativistically hot electron-ion fraction temperature and the magnetofluid coupling. It is shown that for realistic physical parameters of White Dwarfs accreting hot astrophysical flow /Binary systems there always exists such a real solution of the dispersion relation for which the formation of dispersive strong super-Alfvenic macroscale flow/outflow with Alfven-Mach number >10(6) and/or generation of superstrong magnetic fields is guaranteed.
