Abstract This work explores the construction of spherically symmetric models of stellar interiors by incorporating the null complexity factor (CF) as an additional constraint. This supplementary condition helps us to close an array of stellar structu

Abstract Building on the Einasto dark matter (DM) density parameterizations, this study explores the possibility of constructing DM black holes (BHs) within the formalism of the Starobinsky gravity model. This approach extends the solutions character

Abstract Anisotropic spherically symmetric solutions within the framework of the Brans–Dicke theory are uncovered through a unique gravitational decoupling approach involving a minimal geometric transformation. This transformation effectively divid

Abstract This paper investigate the impacts of local density perturbations on the stability of self-gravitating compact objects by utilizing cracking technique within the context of f(R, T) gravity, where R and T represent the Ricci scalar, and the t

In this manuscript, we study the construction of static cylindrically symmetric thin shell wormhole models with an electric charge in the background of f(R,T) gravity. We utilized “cut and paste” technique to match two identical spacetimes across

Abstract Despite coming across quite effective definitions of complexity in terms of many modified theories of gravity, it still has a question about its existence in f(T) gravity, where the torsion scalar T is accountable for gravitational impacts.

Abstract The objective of this paper is to investigate the continuation of Lemaître–Tolman–Bondi (LTB) space-time for dissipative dust configuration in the direction of Palatini f(R) theory. In this context, the generalized form of field and dyn
