Complex Wave Numbers in the Vicinity of the Schwarzschild Event Horizon
M. Sharif, Umber Sheikh
This paper is devoted to investigate the cold plasma wave properties outside the event horizon of the Schwarzschild planar analogue. The dispersion relations are obtained from the…
Isothermal Plasma Waves in Gravitomagnetic Planar Analogue
M. Sharif, Umber Sheikh
We investigate the wave properties of the Kerr black hole with isothermal plasma using 3+1 ADM formalism. The corresponding Fourier analyzed perturbed GRMHD equations are used to o…
Effects of Schwarzschild Black Hole Horizon on Isothermal Plasma Wave Dispersion
M. Sharif, Umber Sheikh
The 3+1 GRMHD equations for Schwarzschild spacetime in Rindler coordinates with isothermal state of plasma are formulated. We consider the cases of non-rotating and rotating backgr…
Cold Plasma Dispersion Relations in the Vicinity of a Schwarzschild Black Hole Horizon
M. Sharif, Umber Sheikh
We apply the ADM 3+1 formalism to derive the general relativistic magnetohydrodynamic equations for cold plasma in spatially flat Schwarzschild metric. Respective perturbed equatio…
