Ergosphere of a black hole
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. WebAug 16, 2024 · As black holes spin, they literally drag on space-time around them, creating a region around the event horizon — the point beyond which nothing can escape — known as the ergosphere. Inside...

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.
