We analytically explore the effects of the gravitational electromotive force on magnetic reconnection around Schwarzschild black holes through a generalized general-relativistic magnetohydrodynamic model that retains two-fluid effects. It is shown that the gravitational electromotive force can couple to collisionless two-fluid effects and drive magnetic reconnection. This is allowed by the departure from quasi-neutrality in curved spacetime, which is explicitly manifested as the emergence of an…

Anisotropic pressure effects in hydrodynamic description of waves propagating parallel to the magnetic field in relativistically hot plasmas

The structure of novel hydrodynamic model of plasmas with the relativistic temperatures consisted of four equations for the material fields is presented for the regime of anisotropic pressure and

Magnetic reconnection as a mechanism for energy extraction from rotating black holes

Spinning black holes store rotational energy that can be extracted. When a black hole is immersed in an externally supplied magnetic field, reconnection of magnetic field lines within the ergosphere

Nonlinear Coupling of Electromagnetic and Spin-Electron-Acoustic Waves in Spin-polarized Degenerate Relativistic Astrophysical Plasma

Propagation of the finite amplitude electromagnetic wave through the partially spin-polarized degenerate plasmas leads to the instability. The instability happens at the interaction of the

Spin-electron-acoustic waves and solitons in high-density degenerate relativistic plasmas

Spin-electron-acoustic waves (sometimes called spin-plasmons) can be found in degenerate electron gases if spin-up electrons and spin-down electrons move relatively each other. Here, we suggest

The ideal magnetohydrodynamic theorem on the conservation of the magnetic connections between plasma elements is extended to nonideal relativistic plasmas in curved spacetime. The existence of



Collisionless Magnetic Reconnection in Curved Spacetime and the Effect of Black Hole Rotation

Magnetic reconnection in curved spacetime is studied by adopting a general relativistic magnetohydrodynamic model that retains collisionless effects for both electron-ion and pair plasmas. A simple

A fundamental interaction between gravity and magnetic reconnection in astrophysical contexts is established, taking into account the effect of spacetime curvature.


To study phenomena of plasmas around rotating black holes, we have derived a set of 3+1 formalism of generalized general relativistic magnetohydrodynamic (GRMHD) equations. In particular, we

Thermal-inertial effects on magnetic reconnection in relativistic pair plasmas.

It is found that in both Sweet-Parker and Petschek relativistic scenarios there is an increase of the reconnection rate owing to the thermal-inertial effects, implying that reconnection can be achieved even for vanishing resistivity as a result of only thermal- inertIAL effects.

A new covariant connection equation is derived showing the existence of generalized magnetofluid connections that are preserved during the dissipationless plasma dynamics.

Two-scale structure of the electron dissipation region during collisionless magnetic reconnection.

Particle-in-cell simulations of collisionless magnetic reconnection are presented that demonstrate that reconnection remains fast in very large systems. The electron dissipation region develops a

The laws of perfect general-relativistic magnetohydrodynamics are rewritten in 3+1 language in a general spacetime and should be of interest in numerical relativity, numerical astrophysics, and the membrane paradigm for black holes.

Influence of frame-dragging on magnetic null points near rotating black holes

Understanding the mechanisms of particle acceleration from the vicinity of black holes poses a challenge. Electromagnetic effects are thought to be a prime suspect, but details still need an

Collisionless magnetic reconnection in a two dimensional plasma is analyzed, using a two-fluid model where electron mass and pressure effects are important. Numerical simulations show the formation

Action Principles for Relativistic Extended Magnetohydrodynamics: A Unified Theory of Magnetofluid Models

Two types of Eulerian action principles for relativistic extended magnetohydrodynamics (MHD) are formulated. With the first, the action is extremized under the constraints of density, entropy, and
