Hawking radiation through tunneling from a hot NUT-Kerr–Newman-Kasuya-Anti-de Sitter black hole

Abstract

In this research work, we examine the tunneling phenomenon of a charged Dirac particle emerging from the thermal horizon of a hot NUT-Kerr–Newman-Kasuya-Anti-de Sitter (HNKNK-AdS) black hole. Using the tunneling formalism, we derive the Hawking temperature associated with the charged Dirac particle at the horizon of the HNKNK-AdS black hole. Our findings reveal that the effective Hawking temperature depends on various black hole parameters, including electric and magnetic charges, magnetic mass, the cosmological constant, and angular momentum. Additionally, the Hawking radiation for the Kerr–Newman black hole diminishes slightly, and a minor correction to the thermal radiation is identified. We also discuss the heat capacities of the HNKNK-AdS and find that there exists an infinite number of discontinuity implying that the black hole system becomes unstable as the smaller the event horizon of the black hole and hence deduces the well-known heat capacity for the Kerr–Newman black hole.
