Hayward black hole
WebApr 16, 2024 · The Hayward black hole. To derive regular spacetime solutions from general relativity, when coupling with a non-linear electromagnetic field is present, we encounter the action [ 13 – 16] where κ = 8 πG / c4, with G as the Newton gravitational constant and c as the speed of light. WebApr 2, 2024 · We present an exact nonsingular black hole solution in the $4D$ EGB gravity coupled to non-linear electrodynamics and analyze their thermodynamic properties to calculate precise expressions for the black hole mass, temperature, and entropy. Because of the magnetic charge, the thermodynamic quantities are corrected, and the Hawking- …

WebThis is a list of known black holes that are close to the Solar System, which Earth is part of.. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more distant objects. As of … WebSep 10, 2024 · In this letter we use the Carathéodory's approach to thermodynamics, to construct the thermodynamic manifold of the Hayward black hole. The Pfaffian form representing the infinitesimal heat exchange reversibly is considered to be δ Q rev ≡ d r s − F H d l, previously obtained by Molina & Villanueva [1], where r s is the Schwarzschild …

Web1 day ago · The Bardeen and Hayward spacetimes are here considered as standard configurations of spherically symmetric regular black holes. Assuming the thermodynamics of such objects to be analogous to standard black holes, we compute the island formula in the regime of small topological charge and vacuum energy, respectively for Bardeen and …
WebThe Schwarzschild solution, taken to be valid for all r > 0, is called a Schwarzschild black hole. It is a perfectly valid solution of the Einstein field equations, although (like other black holes) it has rather bizarre properties. For r < r s the Schwarzschild radial coordinate r becomes timelike and the time coordinate t becomes spacelike. spinning picture framesWebThe Black Hole. Sep 1995 - Present27 years 3 months.
