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…
