Interplay of Null Energy Condition Violations and Thermodynamics in Kiselev Black Hole Evaporation
Vitalii Vertogradov, Maksim Grigorev
The evaporation of black holes with two horizons presents a rich thermodynamic landscape that departs fundamentally from the Schwarzschild paradigm. In this work, we analyze the Ha…
Energy Extraction and Evolution of Regular Black Holes: The Case of Bardeen Spacetime
Vitalii Vertogradov, Angel Rincon
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 c…
Barotropic Equation of State and Nonlinear Electrodynamics in Dynamical Black Hole Spacetimes
Vitalii Vertogradov, Dmitriy Kudryavtcev
Models of black holes that differ from idealized vacuum and electrovacuum solutions of Einstein's equations often contain parameters whose physical interpretation is unclear. Howev…
Gravitational Collapse and Formation of Regular Black Holes: Dymnikova, Hayward, and Beyond
Vitalii Vertogradov
The gravitational collapse of a star can lead to the formation of a regular black hole. However, a key factor in this process is the transition of ordinary baryonic matter into a s…
Regular Black Hole Models in the Transition from Baryonic Matter to Quark Matter
Vitalii Vertogradov, Ali Övgün
In this paper, we investigate gravitational collapse scenarios involving baryonic matter transitioning into quark-gluon plasma under extreme astrophysical conditions, focusing on t…
Formation of regular black hole from baryonic matter
Vitalii Vertogradov, Ali Övgün, Daniil Shatov
We present a family of exact, singularity-free solutions describing the collapse of baryonic matter characterized by a barotropic equation of state whose coefficient varie…
