Definition of Complexity Factor for Self-Gravitating Systems in Palatini Gravity
Z. Yousaf
The aim of this paper is to explore the complexity factor (CF) for those self-gravitating relativistic spheres whose evolution proceeds non-dynamically. We are adopting the definit…
Influence of Modification of Gravity on the Complexity Factor of Static Spherical Structures
Z. Yousaf, Maxim Yu. Khlopov, M. Z. Bhatti +1
The aim of this paper is to generalize the definition of complexity for the static self-gravitating structure in gravitational theory, where is the Ricci scalar, …
Dynamical Analysis of Self-gravitating Stars in Modified Gauss-Bonnet Gravity
M. Z. Bhatti, Z. Yousaf, A. Khadim
In this paper, we have continued the work of Herrera \emph{et al.} \cite{herrera2012dynamical} in gravitational theory. For this purpose, a spherically symmetric fluid exhib…
The Measure of Complexity in Charged Celestial Bodies in Gravity
Z. Yousaf, M. Z. Bhatti, T. Naseer +1
In this paper, we investigate irregularities in a cylindrical self-gravitating system which contains the properties of an imperfect matter and electromagnetic field. For …
Gravastars in Gravity
M. Z. Bhatti, Z. Yousaf, A. Rehman
In this paper, we discuss some feasible features of gravastar that were firstly demonstrated by Mazur and Mottola. It is already established that gravastar associates the de-Sitter…
Measure of Complexity in Self-Gravitating Systems using Structure Scalars
Z. Yousaf, Kazuharu Bamba, M. Z. Bhatti +1
The aim of this paper is to present the definition of complexity for static self-gravitating anisotropic matter proposed in theory, where is the Gauss-Bonnet term and…
New Definition of Complexity Factor in Gravity
Z. Yousaf, M. Z. Bhatti, T. Naseer
This paper is devoted to present new definition of complexity factor for static cylindrically symmetric matter configurations in gravity. For this purpose, we…
Gravastars in Gravity
Z. Yousaf, M. Z. Bhatti, H. Asad
This work is devoted to study the analytical and regular solutions of a particular self-gravitating object (i.e., gravastar) in a particular theory of gravity. We derive the corres…
On the Role of Terms in Structure Scalars
Z. Yousaf
This work is devoted to explore the effects of terms on the study of structure scalars and their influences in the formulations of the Raychaudhuri, shear and Weyl scalar…
