Compact Star Modeling of Durgapal Solution in \(\boldsymbol{f(Q)}\) Gravity
This study uses a specific ansatz within \(f(Q)\) gravity theory to examine the characteristics of spherically symmetric anisotropic compact stars. The research aims at enhance comprehension of these atypical entities by examining the physical properties of the compact star model using the Durgapal geometry within the context of \(f(Q)\) gravity. The \(f(Q)\) gravity field equations are resolved using the Karmarkar condition, and the physical characteristics such as density and pressure are computed for the resulting solution. The energy criteria are fulfilled, and the TOV equations perform the equilibrium analysis. The physical study indicates that our models meet the requirements for a well-behaved stellar system. This indicates that our solution is suitable for modeling astrophysical objects.
期刊介绍:
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
