We generate a new generalized regular charged anisotropic exact model that admits
conformal symmetry in static spherically symmetric spacetime. Our model was examined for …

We find a new family of exact solutions to the Einstein system of equations with an
anisotropic fluid distribution for a spherically symmetric spacetime containing a conformal …

In this paper we employ the Karmarkar condition (Proc Indian Acad Sci A 27: 56, 1948) to
model a spherically symmetric radiating star undergoing dissipative gravitational collapse in …

In order to study the type of collapse mentioned in the title, we introduce a physically
meaningful object, called the horizon function. It directly enters the expressions for many of …

The objective of this study is to investigate spherically symmetric radiating stars undergoing
gravitational collapse, in higher dimensional general relativity, inclusive of acceleration …

This work is devoted to study the evolutionary mechanism for anisotropic dissipative
spherical system in the presence of exotic cosmic energy. The phenomenon of gravitational …

We introduce a physically important object, called the horizon function, in the study of
geodesic collapse. It is closely related to the stellar characteristics and satisfies a simple …

We consider the general case of an accelerating, expanding and shearing model of a
radiating relativistic star using Lie symmetries. We obtain the Lie symmetry generators that …

We consider the general model of an accelerating, expanding and shearing radiating star in
the presence of charge. Using a new set of variables arising from the Lie symmetries of …

The behaviour of a bounded radiating body in general relativity is determined by a nonlinear
boundary condition at the stellar surface. We systematically study the differential equations …
