Solutions for neutron stars in General Relativity from a complexity structure scalar boundary condition

Robert S. Bogadi, Megandhren Govender, Genly Leon +1

A new condition involving the complexity factor, a structure scalar arising from the orthogonal splitting of the Riemann tensor, is generated at the boundary of a spherically symme…

Asymptotic Solutions of Radiating Stars

R. S. Bogadi, G. Leon, M. Govender +3

We investigate the evolution of the surface of radiating stars by studying the asymptotic behaviour of exact solutions initiated via the stationary boundary condition. This boundar…

Anisotropic Spacetimes in -gravity: Bianchi I, Bianchi III and Kantowski-Sachs Cosmologies

R. Bogadi, A. Giacomini, M. Govender +3

We investigate the evolution of cosmological anisotropies within the framework of -gravity. Specifically, we consider a locally rotationally symmetric geometry in…

Lie symmetry approach to the time-dependent Karmarkar condition

Andronikos Paliathanasis, Robert S. Bogadi, Megandhren Govender

We obtain solutions of the time-dependent Einstein Field Equations which satisfy the Karmarkar condition via the method of Lie symmetries. Spherically symmetric spacetime metrics a…

Stability and Horizon Formation during Dissipative Collapse

Nolene F. Naidu, Robert S. Bogadi, Anand Kaisavelu +1

We investigate the role played by density inhomogeneities and dissipation on the final outcome of collapse of a self-gravitating sphere. By imposing a perturbative scheme on the th…

Gravitational collapse in spatially isotropic coordinates

Megan Govender, Robert Bogadi, Ranjan Sharma +1

We investigate the dynamical nature of the collapse process of a spherically symmetric star in quasi-static hydrodynamical equilibrium. The star collapses from an initial static co…
