Webb10 apr. 2024 · Recent work has demonstrated that rotating black holes in dynamical Chern-Simons gravity possess unique structures, the “Chern-Simons caps,” which may influence the behavior of matter near the black hole. Motivated by the presence of these caps, we study superradiance in dynamical Chern-Simons gravity in the context of a slowly … Webb8 jan. 2024 · A phantom Maxwell black hole is investigated in this theory as an example of exact slowly rotating black hole solution. Therefore, formula for angular velocity of the …

The Kerr geometry is often used as a model of a rotating black hole but if the solution is held to be valid only outside some compact region (subject to certain restrictions), in principle, it should be able to be used as an exterior solution to model the gravitational field around a rotating massive object other than a black hole such as a neutron star, or the Earth. This works out very nicely for the non-rotating case, where the Schwarzschild vacuum exterior can be matched to a Schwarzsc… Webb27 juli 2009 · For the case E ADAF =E ISCO (E ADAF = 1), the spin-up curve is positive for j < 0.96 (0.97) and slowly spinning black holes will be spun up as accretion proceeds.
