Relativistic stellar collapse of initially static configurations
Keshlan S. Govinder, Megandhren Govender, Sunil Maharaj
We study the dynamics of a radiating relativistic star in the presence of the electromagnetic field and the cosmological constant. The evolution of the model originates from an ini…
A group theoretic approach to shear-free radiating stars
G. Abebe, S. D. Maharaj, K. S. Govinder
A systematic analysis of the junction condition, relating the radial pressure with the heat flow in a shear-free relativistic radiating star, is undertaken. This is a highly nonlin…
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…
