Ergosphere of a black hole
WebErgosphere - Oxford Reference Overview ergosphere Quick Reference The region just outside the event horizon of a rotating black hole (i.e. a Kerr black hole), within which … WebThis Letter reports on 3-dimensional simulations of Kerr black hole magnetospheres that obey the general relativistic equations of perfect magnetohydrodynamics (MHD). In particular, we study powerful Poynting flux dominated jets that are driven from dense gas in the equatorial plane in the ergosphere.

WebJun 8, 2024 · The ergosphere touches the event horizon at the poles of a rotating black hole and extends to a greater radius at the equator, and depending on the speed of rotation of the black hole, the ...
WebYou can think of the ergosphere as a region where you would have to move faster than the speed of light to stand still. Inside the ergosphere, observers are forced to co-rotate with the black hole. A useful concept for thinking about trajectories in Kerr spacetime are the orthonormal "zero angular momentum observer" (ZAMO) frames. WebKilling Horizon for Kerr Black Hole. I have some confusion about Killing Horizon of BH. Since a Killing Horizon (KH) is a null hyper-surface at which killing vector k μ is null; k μ k μ = 0. For time translation symmetry k μ = ∂ t in Kerr BH case. k μ k μ = ( 1 − 2 M r ρ 2) = 0 ⇒ ρ 2 = 2 M r. Which is static limit surface of Kerr BH.
WebJan 13, 2024 · When a black hole is immersed in an externally supplied magnetic field, reconnection of magnetic field lines within the ergosphere can generate negative energy (relative to infinity) particles that fall into the black hole event horizon while the other accelerated particles escape stealing energy from the black hole. WebIn Figure 2 (left), we illustrate the Feynman diagram of the beta-decay in the ergosphere of rotating black hole which corresponds to MPP in ultra-efficient regime. Neutron decays into proton, electron and antineutrino. Due to expectation of alignment of accretion flow with a black hole rotation at least near the event horizon, gravitationally ...
