Exploring Absolute Retract in Regular Hayward Black Holes and Their Implications for Astrophysics
In this article, we study and describe the topology of the spherically symmetric and regular (with no singularity in its event horizon) black hole, which is called Hayward black hole. We use the symmetric metric for this object, associated with the Euler-Lagrangian equation, to derive various types of geodesic equations and components of a subspace geodesic. Under certain conditions, this approach allows us to deduce three types of absolute retractions representing the particle's motion along different axes within a 3-D subspace. These retractions could potentially describe the region of the event horizon of Hayward black holes. We show that the radial geodesics describe motion directly toward the black hole's center, while tangential geodesics illustrate paths without angular displacement. Spacetime curvature near the event horizon emphasizes the intense gravitational effects and distortions caused by the black hole's mass. Particle motion in subspace represents constrained tangential dynamics, providing insights into localized spacetime. In addition, the study of the Hayward black hole (topology and geometry) is valuable for our understanding of general relativity, exploring the quantum field of gravity implications, and contribute to the fields of mathematical physics and astrophysics.
期刊介绍:
Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
