Macroscale fast flow and magnetic-field generation in two-temperature relativistic electron–ion plasmas of astrophysical objects

نویسندگان

چکیده

We have shown the simultaneous generation of macro-scale fast flows and strong magnetic fields in 2-temperature relativistic electron-ion plasmas astrophysical objects due to Unified Reverse Dynamo/Dynamo mechanism. The resulting dynamical field amplification and/or flow acceleration is directly proportional initial turbulent kinetic/magnetic (magnetic) energy; process very sensitive relativistically hot fraction temperature magneto-fluid coupling. It shown, that for realistic physical parameters White Dwarfs accreting / Binary systems there always exists such a real solution dispersion relation which formation dispersive super-Alfv\'enic flow/outflow with Alfv\'en Mach number $> 10^6$ super-strong guaranteed.

Conditions for fast magnetic reconnection in astrophysical plasmas

We investigate favourable circumstances for fast magnetic reconnection in astrophysical plasmas based on recent results by Rogers et al. (2001). Given that a critical magnetic field structure with antiparallel field lines exists, our analysis demonstrates that a sufficient condition for fast reconnection is that the ratio of the thermal pressure to the magnetic field pressure β should be signif...

Magnetic Reconnection in Astrophysical and Laboratory Plasmas

Magnetic reconnection is a topological rearrangement of magnetic field that converts magnetic energy to plasma energy. Astrophysical flares, from the Earth’s magnetosphere to γ -ray bursts and sawtooth crashes in laboratory plasmas, may all be powered by reconnection. Reconnection is essential for dynamos and the large-scale restructuring known as magnetic self-organization. We review reconnect...

Turbulence and Magnetic Fields in Astrophysical Plasmas

Magnetic fields permeate the Universe. They are found in planets, stars, accretion discs, galaxies, clusters of galaxies, and the intergalactic medium. While there is often a component of the field that is spatially coherent at the scale of the astrophysical object, the field lines are tangled chaotically and there are magnetic fluctuations at scales that range over orders of magnitude. The cau...

Magnetic field generation in relativistic shocks

We present an analytical estimate for the magnetic field strength generated by the Weibel instability in ultra-relativistic shocks in a hydrogen plasma. We find that the Weibel instability is, by itself, not capable of converting the kinetic energy of protons penetrating the shock front into magnetic field energy. Other (nonlinear) processes must determine the magnetic field strength in the wak...

Magnetic fields in astrophysical objects.

Magnetic fields are known to reside in many astrophysical objects and are now believed to be crucially important for the creation of phenomena on a wide variety of scales. However, the role of the magnetic field in the bodies that we observe has not always been clear. In certain situations, the importance of a magnetic field has been overlooked on the grounds that the large-scale magnetic field...
