We review and discuss possible causes for the appearance of local anisotropy (principal
stresses unequal) in self-gravitating systems and present its main consequences. We …

Abstract The Einstein–Maxwell (or Einstein) system of field equations plays a substantial
role in the modeling of compact stars. Although due to its non-linearity getting an exact …

The Effect of Gravitational Decoupling on Constraining the Mass and Radius for the Secondary
Component of GW190814 and Other Self-bound Strange Stars in f(Q) Gravity Theory …

We put forward a new definition of complexity, for static and spherically symmetric self-
gravitating systems, based on a quantity, hereafter referred to as complexity factor, that …

The main objective of this work, is to develop a novel general framework for generating
solutions of stellar models in f (R) theory of gravity with class one metric. Such framework is …

Using the concept of cracking we explore the influence that density fluctuations and local
anisotropy have on the stability of local and non-local anisotropic matter configurations in …

We present a class of exact solutions of Einstein's gravitational–field equations describing
spherically symmetric and static anisotropic stellar–type configurations. The solutions are …

It is shown that for realistic anisotropic star models the surface redshift cannot exceed the
values 3.842 or 5.211 when the tangential pressure satisfies the strong or the dominant …

In this work we build a relativistic anisotropic admissible compact structures. To do so we
combine the class I approach with gravitational decoupling in order to generate the …

This article is devoted to the study of high dense charged anisotropic compact structures in
the framework of f (R, T) gravity theory. The principal aims of this investigation, regard the …
