An Eternal gravitational collapse in theory of gravity and their astrophysical implications
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +1
In this work, we explore the eternal collapsing phenomenon of a stellar system (e.g., a star) within the framework of gravity and investigate some new aspects of the continu…
Black hole formation in gravitational collapse and their astrophysical implications
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +2
In this work, we have investigated a novel aspect of black hole (BH) formation during the collapse of a self-gravitating configuration. The exact solution of the Einstein field equ…
Astrophysical implications of an eternal homogeneous gravitational collapse model with a parametrization of expansion scalar
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +1
In this study, we continue our previous work (Annu et al., 2023) by introducing a novel parametrization of the expansion scalar as a rational function of cosmic time . The p…
Spherically symmetric gravitational collapse in the background of Chaplygin gas
Anjali Pandey, Rajesh Kumar, Sudhir Kumar Srivastava
This paper considers the spherically symmetric gravitational collapse in the background of Chaplygin gas as dark energy component. The dark energy is assumed to be generalized and…
Eternal homogeneous gravitational collapse: A comprehensive analysis from parametrization
Annu Jaiswal, Rajesh Kumar, Sudhir Kumar Srivastava +1
A new class of self-gravitating collapsing star models with perfect fluid distributions is discussed in this work. The paper has a comprehensive analysis of a homogeneous gravitati…
Spherically Symmetric Gravitational Collapse Of Inhomogeneous Dust Cloud In The Background Of Dark Energy
Anjali Pandey, Rajesh Kumar, Sudhir Kumar Srivastava
The present paper deals with the gravitational collapse of an inhomogeneous spherical star consisting of dust fluid in the background of dark energy components with linear equation…
Dynamics of expansion free self gravitating cylindrically symmetric radiating star
Rajesh Kumar, Sudhir Kumar Srivastava
The present work deals with the dynamics of radiating star which is considered to be expansion free cylindrical symmetric dust dissipative fluids. Several treatments are adopted fo…
Dynamical model of expansion free dissipative perfect fluids in general relativity
Rajesh Kumar, S. K. Srivastava
This paper deals with the spherically symmetric self-gravitating star which is considered to be expansion free dissipative perfect fluids distribution. Some recent research reveals…
