Generalized Euclidean stars with equation of state
G. Z. Abebe, S. D. Maharaj, K. S. Govinder
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 leav…
Geodesic models generated by Lie symmetries
G. Z. Abebe, S. D. Maharaj, K. S. Govinder
We study the junction condition relating the pressure to the heat flux at the boundary of a shearing and expanding spherically symmetric radiating star when the fluid particles are…
The Deng algorithm in higher dimensions
Y. Nyonyi, S. D. Maharaj, K. S. Govinder
We extend an algorithm of Deng in spherically symmetric spacetimes to higher dimensions. We show that it is possible to integrate the generalised condition of pressure isotropy and…
Lie symmetries for a conformally flat radiating star
G. Abebe, K. S. Govinder, S. D. Maharaj
We consider a relativistic radiating spherical star in conformally flat spacetimes. In particular we study the junction condition relating the radial pressure to the heat flux at t…
New charged shear-free relativistic models with heat flux
Y. Nyonyi, S. D. Maharaj, K. S. Govinder
We study shear-free spherically symmetric relativistic gravitating fluids with heat flow and electric charge. The solution to the Einstein-Maxwell system is governed by the general…
Higher dimensional charged shear-free relativistic models with heat flux
Y. Nyonyi, S. D. Maharaj, K. S. Govinder
We analyse shear-free spherically symmetric relativistic models of gravitating fluids with heat flow and electric charge defined on higher dimensional manifolds. The solution to th…
