Higher Dimensional Inhomogeneous Perfect Fluid Collapse in \emph{f(R)} Gravity
G. Abbas, M. S. Khan, Zahid Ahmad +1
This paper is about the -dimensional gravitational contraction of inhomogeneous fluid without heat flux in the framework of metric theory of gravity. Matching condition…
Gravitational Dust Collapse in Gravity
M. Farasat Shamir, Zahid Ahmad, Zahid Raza
This paper is devoted to investigate gravitational collapse of dust in metric gravity. We take FRW metric for the interior region while the Schwarzchild spacetime is conside…
Collapsing Plane Symmetric Source with Heat Flux and Conformal Flatness
G. Abbas, Zahid Ahmad, Hassan Shah
This paper deals with the study of collapsing plane symmetric source in the presence of heat flux. For this purpose, we have calculated the Einstein field equations as well as Weyl…
High-Speed Collapse of a Hollow Sphere of Type I Matter
Zahid Ahmad, Tomohiro Harada, Ken-ichi Nakao +1
In this paper, we study the dynamics of a hollow spherical matter collapsing with very large initial velocity. The spacetime is initially very similar to the Vaidya solution, and t…
Plane Symmetric Gravitational Collapse
M. Sharif, Zahid Ahmad
In this paper, we derive the general formulation by considering two arbitrary plane symmetric spacetimes using Israel's method. As an example, we apply this formulation to known pl…
High-Speed Cylindrical Collapse of Two Perfect Fluids
M. Sharif, Zahid Ahmad
In this paper, the study of the gravitational collapse of cylindrically distributed two perfect fluid system has been carried out. It is assumed that the collapsing speeds of the t…
