Energy Extraction and Evolution of Regular Black Holes: The Case of Bardeen Spacetime (2508.14489v1)
Published 20 Aug 2025 in gr-qc
Abstract: This paper examines regular black holes, in particular the Bardeen spacetime where singularities are replaced by non-singular cores. It explores the energy extraction through the charged Penrose process and shows that magnetic charge evaporation can drive a regular black hole towards a singularity. Two evaporation models are proposed, dealing with charge loss and combined charge evaporation with mass accretion, providing insights into the evolution and stability of regular black holes.
