Modeling of immense gravity objects via generalized solution of Einstein’s field equations
Abstract
In this paper, we generate a new generalized solution for modeling of compact anisotropic astrophysical configurations by using Karmarkar condition of embedded class 1 spacetime manifold. We demonstrate that the new solution satisfies all required physical conditions. We investigate several physical properties of compact star models, i.e. Vela X-1 (Mass M=1.77M=1.77M⊙M⊙, radius = 9.569.56km), PSRJ 1903+3271903+327 (Mass M=1.667M=1.667M⊙M⊙, radius = 9.4389.438km) and PSRJ 0348+04320348+0432 (Mass M=2.01M=2.01M⊙M⊙, radius = 13.113.1km) in conformity with the observational data. The proposed solution is free from singularities, satisfies causality condition and displays well-behaved nature inside the anisotropic configurations. All energy conditions and hydrostatic equilibrium condition are well defined inside the anisotropic fluid spheres. The adiabatic index throughout the stellar interior is greater than 4/34/3 and the compactification factor lies within the Buchdahl limit (M/R≤4/9)(M/R≤4/9). We study the physical features of the solution in detail, analytically as well as graphically for compact star Vela X-1 with nn ranging from 00 to 4.74.7.
